Genes affected

KRT73 (HGNC:28928): (keratin 73) Keratins are intermediate filament proteins responsible for the structural integrity of epithelial cells and are subdivided into epithelial keratins and hair keratins. This gene encodes a protein that is expressed in the inner root sheath of hair follicles. The type II keratins are clustered in a region of chromosome 12q13.[provided by RefSeq, Jun 2009]

The c.857C>G (p.S286C) alteration is located in exon 5 (coding exon 5) of the KRT73 gene. This alteration results from a C to G substitution at nucleotide position 857, causing the serine (S) at amino acid position 286 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
