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]

Ambry Genetics

May 01, 2024

The c.1579A>G (p.K527E) alteration is located in exon 9 (coding exon 9) of the KRT73 gene. This alteration results from a A to G substitution at nucleotide position 1579, causing the lysine (K) at amino acid position 527 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
