Genes affected

KRT76 (HGNC:24430): (keratin 76) Keratins are intermediate filament proteins responsible for the structural integrity of epithelial cells and are subdivided into epithelial keratins and hair keratins. The type II keratins are clustered in a region of chromosome 12q13. [provided by RefSeq, Jun 2009]

The c.1331A>G (p.N444S) alteration is located in exon 7 (coding exon 7) of the KRT76 gene. This alteration results from a A to G substitution at nucleotide position 1331, causing the asparagine (N) at amino acid position 444 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
