Genes affected

KRT79 (HGNC:28930): (keratin 79) 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 an epithelial keratin that is expressed in skeletal muscle, skin and scalp. The type II keratins are clustered in a region of chromosome 12q13.[provided by RefSeq, Jun 2009]

The c.1393G>A (p.V465I) alteration is located in exon 8 (coding exon 8) of the KRT79 gene. This alteration results from a G to A substitution at nucleotide position 1393, causing the valine (V) at amino acid position 465 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
