Pleiotropy01:33

Pleiotropy

Pleiotropy is the phenomenon in which a single gene impacts multiple, seemingly unrelated phenotypic traits. For example, defects in the SOX10 gene cause Waardenburg Syndrome Type 4, or WS4, which can cause defects in pigmentation, hearing impairments, and an absence of intestinal contractions necessary for elimination. This diversity of phenotypes results from the expression pattern of SOX10 in early embryonic and fetal development. SOX10 is found in neural crest cells that form melanocytes,...
Genomic Imprinting and Inheritance02:30

Genomic Imprinting and Inheritance

Diploid organisms inherit genetic material through chromosomes from both parents. Copies of the same gene are known as alleles. In most cases, both alleles are simultaneously expressed and allow various cellular processes to function optimally. If one of the alleles is missing or mutated, the expression of the other allele can compensate; however, this is not true for all genes.
The expression of some genes depends on which parent passed the gene to the offspring, through a phenomenon known as...

Gene-Environment Interactions01:20

Gene-Environment Interactions

Gene expression is a dynamic process that is significantly influenced by environmental factors. This interaction underlies the complex nature of biological development and the phenotypic differences observed among individuals, even among those with identical genetic makeups. Factors such as radiation, temperature, behavior, nutrition, and stress play pivotal roles in determining how genes are expressed. The concept of the reaction range is central to understanding this interaction. It posits...
Unrenewable Cells00:50

Unrenewable Cells

In humans, the photoreceptor cells of the eye and sensory hair cells of the ear lack stem cells. These cells are thus unrenewable and cannot be replaced when they are damaged or destroyed.
Photoreceptors
The retina is composed of several layers and contains specialized cells called photoreceptors. The photoreceptors (rods and cones) change their membrane potential when stimulated by light energy. There are two types of photoreceptors—rods and cones—which differ in the shape of their outer...
Hearing01:31

Hearing

When we hear a sound, our nervous system is detecting sound waves—pressure waves of mechanical energy traveling through a medium. The frequency of the wave is perceived as pitch, while the amplitude is perceived as loudness.

Summary

Hereditary hearing impairment (HI) involves hundreds of genes, with about 50 identified causative genes and 150 mapped loci. This review focuses on genetic syndromes associated with hearing loss, particularly those involving craniofacial malformations.

Area of Science:

  • Genetics
  • Otolaryngology
  • Medical Syndromes

Background:

  • Hearing is a complex process influenced by numerous genes.
  • Genetic mutations are a significant cause of hereditary hearing impairment (HI).
  • Over 150 loci for HI disorders have been mapped, with approximately 50 causative genes identified.

Purpose of the Study:

  • To provide an updated report on genetic syndromes involving hearing impairment.
  • To specifically highlight syndromes associated with external ear and craniofacial malformations.

Main Methods:

  • Analysis of clinical findings in syndromal hearing impairment.
  • Review of neuroradiological findings in syndromal hearing impairment.

Main Results:

  • Genetic factors play a crucial role in syndromal hearing impairment.
  • External ear and craniofacial malformations are frequently associated with genetic hearing loss syndromes.

Conclusions:

  • Genetic diagnosis of HI has significant implications for prognosis, management, and recurrence risk.
  • Molecular diagnosis enables early prenatal diagnosis for severe syndromes.
  • Collaboration between pediatric otolaryngologists, clinical geneticists, and neuroradiologists is essential.
