Inheritance of Fuchs' combined dystrophy
Ophthalmology
|October 1, 1979
Summary
Fuchs
Area of Science:
- Ophthalmology
- Genetics
- Cell Biology
Background:
- The inheritance pattern of Fuchs' combined corneal dystrophy is not well-established.
- Previous studies suggest a female predilection and lack clear segregation patterns.
Observation:
- A novel pedigree revealed 16 affected individuals across four generations.
- Affected individuals showed a 1:1 male to female ratio and 100% penetrance.
- Corneal tissue analysis confirmed Fuchs' dystrophy in multiple generations.
Findings:
- Fuchs' combined corneal dystrophy follows an autosomal dominant inheritance pattern.
- The condition exhibits complete penetrance and a balanced sex ratio.
Implications:
- This finding clarifies the genetic basis of Fuchs' dystrophy.
- Establishes a classic autosomal dominant model for this corneal disease.

Overview
01:33Pleiotropy
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,...
01:43Sex-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.
01:23Cystic Fibrosis: Pathogenesis
Cystic fibrosis (CF), an autosomal recessive disorder, significantly affects the function of exocrine glands. This genetically inherited disease is characterized by the production of thick and sticky mucus, which can severely affect various organs and systems in the body.
CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation, but...

01:21Huntington Disease l: Introduction
Huntington disease or HD is a progressive, fatal neurodegenerative disorder inherited in an autosomal dominant pattern.PathophysiologyIt is caused by expansion of the CAG trinucleotide repeat in the HTT gene on chromosome 4 (4p16.3), producing an abnormal huntingtin protein with an expanded polyglutamine tract. This misfolded protein disrupts cellular function, leading to neuronal death. Normal alleles have ≤26 repeats, 27–35 are intermediate (risk of expansion), 36–39 show reduced penetrance,...
