Genes affected

KRT14 (HGNC:6416): (keratin 14) This gene encodes a member of the keratin family, the most diverse group of intermediate filaments. This gene product, a type I keratin, is usually found as a heterotetramer with two keratin 5 molecules, a type II keratin. Together they form the cytoskeleton of epithelial cells. Mutations in the genes for these keratins are associated with epidermolysis bullosa simplex. At least one pseudogene has been identified at 17p12-p11. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Likely_pathogenic. Variant got 9 ACMG points.

• PVS1: Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
• PP5: Variant 17-41586520-AGC-A is Pathogenic according to our data. Variant chr17-41586520-AGC-A is described in ClinVar as [Pathogenic]. Clinvar id is 66337.Status of the report is no_assertion_criteria_provided, 0 stars.
