Genes affected

KRT15 (HGNC:6421): (keratin 15) The protein encoded by this gene is a member of the keratin gene family. The keratins are intermediate filament proteins responsible for the structural integrity of epithelial cells and are subdivided into cytokeratins and hair keratins. Most of the type I cytokeratins consist of acidic proteins which are arranged in pairs of heterotypic keratin chains and are clustered in a region on chromosome 17q21.2.

Ambry Genetics

Dec 14, 2022

The c.122G>A (p.S41N) alteration is located in exon 1 (coding exon 1) of the KRT15 gene. This alteration results from a G to A substitution at nucleotide position 122, causing the serine (S) at amino acid position 41 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
