Exploring Hearing Function Through Genetics

Aira on March 1, 2024

Hearing function is a vital sense connecting us to the world. It allows us to appreciate music, understand conversations, and navigate our surroundings safely. It refers to recognizing and understanding sounds through a coordinated process involving different parts of your ear and auditory system.

What Happens in the Hearing Process?

In the process of hearing, various components of the ear and auditory system work together to transform sound waves into the perceptions of sound that our brains recognize.

Outer Ear: Sound waves travel through the air and enter the ear canal, which funnels them towards the eardrum.
Middle Ear: The eardrum vibrates in response to the sound waves, transmitting the vibrations to three tiny bones called the ossicles. These bones amplify the vibrations.
Inner Ear: The amplified vibrations reach the cochlea, a snail-shaped structure filled with fluid and lined with tiny hair cells.
Hair Cells and the Auditory Nerve: The vibrations cause the hair cells to bend, triggering the release of electrical signals. These signals travel along the auditory nerve to the brain.
Brain Interpretation: The brain receives the electrical signals and interprets them as sound, allowing us to perceive different pitches, volumes, and tones.

The Importance of Healthy Hearing

Healthy hearing is integral to our everyday lives. Beyond the simple act of hearing, it directly impacts our communication, safety, and overall well-being.

Communication and Connection: Healthy hearing is fundamental for effective communication. It enables us to understand conversations, participate in discussions, and build meaningful relationships. Hearing loss can lead to social isolation, frustration, and misunderstandings.
Cognitive Function: Research suggests a link between hearing loss and cognitive decline. Studies have shown an increased risk of dementia and cognitive impairment in individuals with untreated hearing loss. Maintaining healthy hearing may help protect cognitive function as we age.
Physical and Mental Wellbeing: Hearing loss can negatively impact mental and physical health. It can contribute to feelings of anxiety, depression, and loneliness. Additionally, difficulty hearing warning signals or sounds in traffic can increase the risk of accidents and injuries.
Overall Quality of Life: Healthy hearing enriches our daily lives. It allows us to appreciate the nuances of music, enjoy conversations with loved ones, and stay alert to our surroundings. Hearing loss can significantly diminish these experiences and negatively impact our overall quality of life.

Genetics of Hearing Function

SIK3 Gene

The salt-inducible kinase 3 (SIK3) gene emerges as a pivotal player in shaping hearing function. A genome-wide association analysis identified a single nucleotide polymorphism (SNP) (rs681524) within intron 6 of SIK3. This association, supported by robust statistical significance, suggests a genetic link to hearing function.

NID2

In the context of Age-Related Hearing Impairment (ARHI), NID2 and its genetic variant rs1566129 were prominent among the 44 genome-wide significant loci identified in a large study involving over 250,000 participants from the UK Biobank. This study also uncovered NID2’s involvement in metabolic, sensory, and neuronal functions through immunohistochemistry for protein localization in the adult mouse cochlea.

This discovery provides a concrete basis for exploring NID2 as a potential target for further investigations and interventions to address the multifaceted aspects of ARHI.

ARHGEF28

Also under age-related hearing impairment (ARHI), ARHGEF28 stands out as a significant gene. Previous studies have demonstrated a role for ARHGEF28 in the regulation of neurofilaments, and axon growth and branching. Two independent SNP associations were found within close to the ARHGEF28 locus The study not only expanded the repertoire of established trait loci but also ventured into genetic correlations of hearing function with psychological traits.

ARHGEF28’s association with hearing processes and nervous system functions and its genetic correlations with personality and psychological traits highlight its pivotal role in ARHI. This genetic insight opens new avenues for therapeutic exploration, emphasizing the interconnected nature of hearing function and psychological traits.

Non-Genetic Factors Influencing Hearing Function

Hearing function can be influenced by various factors, including the environment and certain conditions. Understanding these elements is key to preserving and maintaining our auditory well-being.

Age

The natural progression of age can bring about a weakening of hearing abilities. Age-related hearing loss can be influenced by various factors, including exposure to loud noises, illnesses, and certain medications.

Chronic pain conditions: Living with chronic pain can heighten fear of future pain or pain worsening.

How Fear Amplifies Pain

The fear of pain not only elicits emotional responses but also plays a role in shaping one’s physical experience. When anticipating or experiencing fear, the brain triggers a “fight or flight” response, diverting resources from healing processes to prepare for potential danger. This makes even minor sensations feel stronger, leading to hypervigilance and potentially increased pain.

This effect is especially pronounced in people with chronic pain. They often develop a negative feedback loop based on past experiences. Seeing, hearing, or imagining pain-related stimuli can trigger fear and anxiety, reinforcing the connection between pain and specific cues. Over time, these cues become pain triggers, causing physical reactions like muscle tension and increased blood pressure, worsening the discomfort.

How Genetics May Influence Fear of Pain

The role of genetics in predisposing individuals to fear of pain has been relatively uncharted territory. A groundbreaking genome-wide association study (GWAS) was conducted to unravel the genetic underpinnings of this phenomenon. This study aimed to identify specific genes that may contribute to varying levels of fear of pain, shedding light on the intricate interplay between our genetic makeup and psychological responses to pain stimuli.

Genes Influencing Fear of Pain

The results of the GWAS unveiled intriguing insights into the genetic architecture of fear of pain. Three distinct genetic loci were significantly associated with fear of minor pain, located at 8q24.13, 8p21.2, and 6q26. These loci are proximal to genes such as TMEM65, NEFM, NEFL, AGPAT4, and PARK2, suggesting a potential link between these genes and the modulation of fear responses to minor pain. Also, an SNP (rs7084783) in gene NEURL1 on chromosome 10 was found to be associated with fear of various levels of pain.

In this section, we dive into the intricate interplay between genes and folate metabolism, exploring key genetic modifiers and their contributions to the regulation of vitamin B9 levels.

MTHFR Gene

The 5,10-methylenetetrahydrofolate reductase (MTHFR) gene, specifically the 677C→T variant (rs1801133), has emerged as a major genetic modifier impacting folate status as also demonstrated by a 2018 study involving 2232 young, healthy Irish subjects. This variant reached genome-wide significance for red blood cell folate, serum folate, as well as plasma total homocysteine concentrations. It played a pivotal role in influencing all three of these critical folate-related indicators.

A second polymorphism within the MTHFR gene, rs3753584, exhibited a significant independent effect on red blood cell folate concentrations. This variant, alongside the primary 677C→T variant, contributed to the complex genetic landscape influencing folate levels in the studied population.

CLCN6 Gene

In 2021, a genome-wide association study with 45 clinically relevant traits from the population of Qatar was performed using a whole genome sequencing (WGS) approach in a discovery set of 6218 individuals with a replication of the findings in 7768 subjects. The study found that the heritability of these traits was similar between Qatari and European populations (r = 0.81). Furthermore, a new gene variant, rs17350396 in CLCN6 (Chloride channel 6), an MTHFR neighbor gene, was found to be significantly associated with serum folate levels. Interestingly, CLCN6 has been associated with neurodegeneration.

These findings underscore the intricate genetic interplay that contributes to variations in folate-related biomarkers and highlight potential novel pathways involved in Vitamin B9 metabolism.

An Overview of Vitamin B12

Vitamin B12, also known as cobalamin, is a water-soluble vitamin that is essential for several physiological processes, such as normal nervous system functioning, red blood cell development, DNA synthesis, and energy metabolism.

It is important to note that the human body cannot produce vitamin B12 on its own, and it must be obtained through diet or supplements. It occurs naturally in animal-based foods like fish, meat, poultry, eggs, and dairy products. For those preferring plant-based options, fortified breakfast cereals and nutritional yeasts are accessible alternatives.

In optimizing Vitamin B12 levels, multivitamin/mineral supplements are also available. Doses vary from 5 to 1,000 mcg (micrograms). The most common form in supplements is cyanocobalamin, with no significant differences in absorption rates among different forms.

Although there are many available sources of vitamin B12, deficiency is still common. General physical symptoms of vitamin B12 deficiency can include feeling very tired or weak, experiencing nausea, vomiting, or diarrhea, not feeling as hungry as usual, weight loss, having a sore mouth or tongue, and yellowish skin.

Importance of Vitamin B12

Let’s dive deeper into the key roles of vitamin B12, and learn how it helps our well-being.

Red Blood Cell Formation

Vitamin B12 is essential for the production and maturation of red blood cells in the bone marrow. These cells are vital for carrying oxygen to tissues and organs throughout the body. A deficiency in B12 can lead to a type of anemia known as megaloblastic anemia, where red blood cells are larger and less functional.

Neurological Function

Vitamin B12 is crucial for maintaining the health of the nervous system. It plays a role in the formation and maintenance of the myelin sheath, a protective covering around nerve fibers that facilitates proper nerve transmission. Deficiencies in B12 can lead to neurological issues, including numbness, tingling, and problems with coordination.

Exploring the Genetic Basis of Loneliness and Its Connection to Mental Well-Being

Aira on February 12, 2024

Overview

Loneliness is a complex and often subjective emotional state characterized by a perceived lack of social connection and meaningful interpersonal relationships. It is vital to differentiate between being alone and feeling lonely; the former refers to a physical state of solitude, while the latter is a psychological experience that can occur even when surrounded by others.

At its core, loneliness is feeling disconnected, isolated, or alienated from others. Sadness, emptiness, and longing for more fulfilling social interactions accompany it. You can experience loneliness in different ways:

Social Loneliness: Social loneliness occurs when an individual lacks a broader social network or community. People experiencing social loneliness might have friends or family but feel disconnected from a wider social circle or community.
Emotional Loneliness: We feel this when there is an absence of a close emotional attachment, such as a deep friendship or intimate partner. Even if someone has many social connections, they might still experience emotional loneliness if these relationships lack emotional depth and intimacy.
Existential Loneliness: A more profound form, existential loneliness is feeling a fundamental sense of emptiness or isolation, questioning our place in the world or the meaning of life.

Loneliness is not inherently a mental health condition. However, chronic or severe loneliness can lead to various mental health challenges like depression, anxiety, and low self-esteem. It can also have physical health implications, such as weakened immune function and increased risk for certain chronic diseases. The experience of loneliness is highly individual, and factors such as personality, life experiences, and external circumstances can influence it.

A 2023 study conducted in the Australian population using data from the Household Income and Labour Dynamics in Australia (HILDA) reported that 34% of individuals experienced loneliness, with 21% facing it episodically and 13% chronically. In contrast, social isolation affected 17% of the population, with 13% experiencing it episodically and 4% chronically.

What Can Loneliness Do to You?

Loneliness can lead to significant emotional distress and has a profound impact on mental health. It often results in feelings of sadness, emptiness, and alienation. Over time, chronic loneliness can contribute to various mental health issues like depression, anxiety, and decreased self-esteem. It also affects physical health, potentially leading to disrupted sleep patterns, increased stress levels, impaired immune function, and an elevated risk of cardiovascular diseases. Socially, it might lead to withdrawal, which can perpetuate a cycle of isolation and loneliness.

Can Loneliness Make You Sick?

Loneliness has been linked to a weakened immune system, making one more susceptible to infections. Studies have shown that loneliness can increase the levels of stress hormones in the body, leading to inflammation and a higher risk of chronic diseases like heart disease. It’s also associated with unhealthy lifestyle choices such as poor diet and lack of physical activity, which can further deteriorate health.

Can Loneliness Cause Depression?

Loneliness is a significant risk factor for depression. The lack of meaningful social connections can lead to feelings of worthlessness and hopelessness, which are central to depression. It can create a vicious cycle where loneliness leads to depression, and depression, in turn, can exacerbate feelings of loneliness. It is important to note that while loneliness can contribute to the development of depression, it is not the sole cause.

Can Loneliness Cause Anxiety?

Loneliness can contribute to the development of anxiety disorders. The feeling of being alone and unsupported can heighten stress and fear, leading to increased anxiety. It can manifest in various forms, such as social anxiety, where individuals fear social interactions, further aggravating their sense of isolation.

What Does Loneliness Do to the Brain?

On a molecular level, loneliness can alter brain chemistry and function. It can lead to increased cortisol, a stress hormone, which affects brain regions like the hippocampus and prefrontal cortex, which are involved in memory and decision-making. Chronic loneliness can also impact the production of neurotransmitters like dopamine and serotonin, which are crucial for mood regulation. It may even influence the expression of genes linked to inflammation, contributing to a heightened inflammatory response.

Can Loneliness Cause Dementia?

Research suggests a potential link between loneliness and an increased risk of dementia. Loneliness can lead to cognitive decline and may accelerate the progression of Alzheimer’s disease and other forms of dementia. This association might be due to increased stress, reduced cognitive engagement, and poorer health behaviors associated with loneliness. However, it is essential to note that while there is a correlation, loneliness is not a direct cause of dementia.

Genetics Of Loneliness

A 2017 study showed the heritability of loneliness to be between 14% and 27%, indicating a role for common genetic variations. The study also observed the highly polygenic nature of loneliness.

A 2020 twin study examined the relationship between loneliness and borderline personality disorder using genetically informative data from adult twin pairs in Australia and the Netherlands, totaling 11,329 individuals. The findings revealed that individual differences in both borderline personality and loneliness were primarily influenced by genetic factors, with heritability estimates of 41% for borderline personality total score and 36% for loneliness. Environmental influences not shared by twins also played a role. Researchers found that the genetic and environmental factors contributing to borderline personality were partially responsible for loneliness as well.

NMUR2

Using the UK Biobank data in a 2018 study, researchers conducted a GWAS on social interaction traits such as attendance at sports clubs, pubs, or religious groups. They found that heritability estimates for these traits were relatively low, similar to other behavioral traits, and identified 38 significant genetic loci across these traits. Some of these loci were also associated with other behavioral and psychiatric traits.

The study also revealed trait-specific genetic correlations. For example, the most strongly associated variant for pub/social club attendance was linked to the alcohol dehydrogenase gene (ADH1B), suggesting a biological basis for this behavior. Another variant associated with sports/gym attendance was the CADM2 gene, known for risk-taking propensity.

The research also found evidence of pleiotropy, where specific genetic loci influence multiple complex traits. For instance, two signals near the BARHL2 and CAMKV genes were associated with various social interaction traits and correlated with other complex traits like educational attainment and inflammatory bowel disease.

The study suggests that social interaction behaviors have a complex genetic architecture and are influenced by unique and shared genetic factors. These findings contribute to understanding the biological underpinnings of social behaviors and their association with other complex traits.

A 2023 proteome-wide analysis study explored the molecular basis of loneliness in the brain by integrating data from the human brain proteomes, transcriptomes, and loneliness GWAS. They identified 18 genes associated with loneliness via their brain protein abundance, with 11 genes replicated in a confirmatory study. They validated four of these genes at the mRNA level. The study also found that increased protein abundance of ALDH2 and ICA1L was protective against loneliness, while GPX1 increased the risk.

Non-Genetic Factors Influencing Loneliness

Non-genetic factors affecting loneliness encompass a range of environmental and personal experiences. Key factors include:

Social Environment: The quality and quantity of social interactions and relationships a person has.
