monilethrix desmoglein 4 DSG4 gene plakoglobin desmosomes hair shaft differentiation autosomal recessive

TLDR New mutations in the DSG4 gene cause a rare hair condition.

The study investigated a Japanese patient with monilethrix, a rare hair condition, and identified novel compound heterozygous mutations in the DSG4 gene: c.624delG (p.M208IfsX4) and c.2468G>A (p.W823X). These mutations were found to affect the DSG4 protein's interaction with plakoglobin, potentially disrupting desmosomes in the hair shaft. This research highlighted the critical role of the DSG4 gene in hair shaft differentiation, contributing to the understanding of the autosomal recessive form of monilethrix.

research A missense mutation in the type II hair keratin hHb3 is associated with monilethrix

79 citations , March 2005 in “Journal of Medical Genetics”

The study investigated the genetic basis of monilethrix, an autosomal dominant hair disorder, by analyzing three patients for mutations in the type II trichocyte keratin genes hHb1, hHb3, and hHb6. While mutations in hHb1 and hHb6 were previously known to be associated with the condition, this study identified a novel heterozygous missense mutation in hHb3 in one patient. This mutation involved the substitution of glutamic acid with lysine at position 407 (E407K) in the helix termination motif, similar to known mutations in hHb1 and hHb6. This finding suggested that hHb3 mutations could also contribute to monilethrix, expanding the understanding of the genetic factors involved in this hair disorder.
