Genes affected

KRT82 (HGNC:6459): (keratin 82) The protein encoded by this gene is a member of the keratin gene family. As a type II hair keratin, it is a basic protein which heterodimerizes with type I keratins to form hair and nails. The type II hair keratins are clustered in a region of chromosome 12q13 and are grouped into two distinct subfamilies based on structure similarity. One subfamily, consisting of KRTHB1, KRTHB3, and KRTHB6, is highly related. The other less-related subfamily includes KRTHB2, KRTHB4, and KRTHB5. All hair keratins are expressed in the hair follicle; this keratin appears to be a hair cuticle-specific keratin. [provided by RefSeq, Jul 2008]

Jun 22, 2024

The c.1118C>T (p.A373V) alteration is located in exon 7 (coding exon 7) of the KRT82 gene. This alteration results from a C to T substitution at nucleotide position 1118, causing the alanine (A) at amino acid position 373 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
