Summary
Pseudopelade is a rare scalp condition causing progressive hair loss. Familial cases suggest it is an autosomal dominant disorder, distinct from other alopecias.
Area of Science:
- Dermatology
- Genetics
Background:
- Pseudopelade is a rare, progressive alopecia without an initial inflammatory phase.
- It is characterized by atrophy, not true scarring, of hair follicles.
- Previously classified with scarring alopecias, its distinct nature is being re-evaluated.
Observation:
- A review of pseudopelade cases, particularly those with a family history, was conducted.
- The study identified familial cases, including a mother and son with pseudopelade.
- These familial instances prompted further investigation into the disorder's etiology.
Findings:
- Clinical and pathological examination supports pseudopelade as a distinct condition.
- A striking familial association was observed in the studied cases.
- This familial link suggests a plausible genetic etiology for pseudopelade.
Implications:
- Pseudopelade is identified as an autosomal dominant disorder.
- The condition specifically affects the scalp, leading to atrophic hair follicle loss.
- Understanding the genetic basis may inform future diagnostic and therapeutic strategies.

Overview
01:39Epistasis
In addition to multiple alleles at the same locus influencing traits, numerous genes or alleles at different locations may interact and influence phenotypes in a phenomenon called epistasis. For example, rabbit fur can be black or brown depending on whether the animal is homozygous dominant or heterozygous at a TYRP1 locus. However, if the rabbit is also homozygous recessive at a locus on the tyrosinase gene (TYR), it will have an unshaded coat that appears white, regardless of its TYRP1...
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,...

Agouti: A Lethal Allele
Lucien Cuénot discovered lethal alleles in 1905 while studying the inheritance of coat color in mice. The agouti gene is responsible for the color of the coat in mice. This gene codes for an agouti-signaling protein, which is responsible for melanin distribution in mammals. The wild-type allele gives rise to gray-brown coat color in mice, while the mutant allele gives rise to yellow coat color. In addition to coat color, the agouti gene is associated with the yellow...

01:20The Retinoblastoma Gene
Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

01:20Accessory Structures of the Skin: Hair Growth and Types
Hair growth begins with the production of keratinocytes by the basal cells of the hair bulb. As new cells are deposited at the hair bulb, the hair shaft is pushed through the follicle toward the surface. Keratinization is completed as the cells are pushed to the skin surface to form the shaft of hair that is externally visible. The external hair is completely dead and composed entirely of keratin. Hair can be cut or shaven without damaging the hair structure because the cut is superficial. Most...
