Cohesins

Cohesins

Cohesin protein complexes are a molecular glue that holds two sister chromatids together. They play an important role both in mitosis and meiosis. In mitosis, all cohesin complexes present on the chromosomes are removed before the start of the anaphase stage.
Cohesin complexes in Meiotic Division
Meiosis involves two distinct rounds of chromosomal segregation and cell divisions— Meiosis I followed by Meiosis II – producing four daughter cells. Meiosis I includes the separation of...

Pleiotropy

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,...

Attachment of Sister Chromatids

Attachment of Sister Chromatids

As cells progress into mitosis, the nuclear envelope breaks down, and the condensed chromosomes are exposed to the array of bipolar microtubules of the mitotic spindle. The kinetochore, a large, disc-shaped protein complex, is present at the centromere region of the sister chromatids and acts as a binding site for the microtubules. Usually, the plus-end of a single microtubule is embedded within the kinetochore. However, some kinetochores first establish lateral contact with the side-wall...

Cystic Fibrosis: Pathogenesis

Cystic 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,...

Sex-linked Disorders

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.

Nondisjunction

Nondisjunction

Nondisjunction is the failure of homologous chromosomes or sister chromatids to separate correctly and move to the opposite poles of the cells. This produces daughter cells with abnormal chromosome numbers. Nondisjunction is common during anaphase I or anaphase II of meiosis. Mutations in synaptonemal complex proteins that attach homologous chromosomes increase the chances of nondisjunction in anaphase I of meiosis I. In contrast, mutations in topoisomerases and condensins that hold...

Clouston's Disease in Three Sisters.

Jayakar Thomas, T C Muthuswami

Indian Journal of Dermatology, Venereology and Leprology

|January 31, 2017

Summary

Three sisters were diagnosed with Clouston's disease, a rare form of hidrotic ectodermal dysplasia. This case highlights a unique presentation within a single generation, with no prior family history of the condition.

Area of Science:

Genetics
Dermatology
Rare Diseases

Background:

Hidrotic ectodermal dysplasia (HED) is a group of genetic disorders affecting ectodermal structures like hair, nails, teeth, and sweat glands.
Clouston's disease, a subtype of HED, is characterized by specific hair, nail, and skin abnormalities.
Genetic inheritance patterns of HED can vary, with autosomal dominant and recessive forms reported.

Observation:

A family with four female children was studied.
Three out of the four sisters presented with symptoms consistent with Clouston's disease.
No other family members across previous generations exhibited signs of HED or Clouston's disease.

Findings:

The affected sisters displayed characteristic features of Clouston's disease.

The inheritance pattern observed was unusual, manifesting solely within a single sibling cohort.

The absence of a family history suggests a potential de novo mutation or incomplete penetrance in prior generations.

Implications:

This case underscores the importance of considering rare genetic conditions even without a clear family history.
Further research into the genetic underpinnings of Clouston's disease may reveal novel mutations or inheritance variations.
Understanding such unique presentations aids in accurate diagnosis and genetic counseling for families with ectodermal dysplasias.
