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,...
Sex Linked Disorders01:43

Sex Linked Disorders

Like autosomes, sex chromosomes contain a variety of genes necessary for normal body function. When a mutation in one of these genes results in biological deficits, the disorder is considered sex-linked.
Polygenic Traits01:18

Polygenic Traits

When more than one gene is responsible for a given phenotype, the trait is considered polygenic. Human height is a polygenic trait. Studies have uncovered hundreds of loci that influence height, and there are believed to be many more. Due to the high number of genes involved, as well as environmental and nutritional factors, height varies significantly within a given population. The distribution of height forms a bell-shaped curve, with relatively few individuals in the population at the...

Cushing Syndrome II: Pathophysiology01:19

Cushing Syndrome II: Pathophysiology

Cortisol production is normally governed by the hypothalamic–pituitary–adrenal (HPA) axis, which maintains hormonal balance through tightly regulated feedback mechanisms. Disruption of this regulatory system is central to the development of Cushing syndrome, whether the excess cortisol originates from external medications or internal pathology. Persistent cortisol elevation alters metabolism, immune function, and endocrine signaling, producing the characteristic clinical features of the...

Area of Science:

  • Genetics
  • Ophthalmology
  • Audiology

Background:

  • Waardenburg syndrome, described by Petrus Johannes Waardenburg in 1951, is a genetic disorder.
  • It is characterized by retinal pigmentary differences, hearing loss, and dystopia canthorum.
  • The condition follows a dominant inheritance pattern with variable clinical presentations.

Purpose of the Study:

  • To report a case of Waardenburg syndrome in a pediatric patient.
  • To describe the clinical presentation including severe bilateral hearing loss and pigmentary disturbances.

Main Methods:

  • Case report.
  • Clinical examination and audiological assessment.

Main Results:

  • A 2-year-old female child presented with Waardenburg syndrome.
  • The patient exhibited severe bilateral hearing loss.
  • Associated pigmentary disturbances were noted.

Conclusions:

  • Waardenburg syndrome can manifest with significant hearing impairment and pigmentary abnormalities.
  • Early diagnosis and management are crucial for affected individuals.
