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

Classification was made for transcript

Our verdict: Likely_benign. The variant received -1 ACMG points.

PP2

Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 39 curated pathogenic missense variants (we use a threshold of 10). The gene has 11 curated benign missense variants. Gene score misZ: 0.8353 (below the threshold of 3.09). Trascript score misZ: 1.2925 (below the threshold of 3.09). GenCC associations: The gene is linked to epidermolysis bullosa simplex 1D, generalized, intermediate or severe, autosomal recessive, Naegeli-Franceschetti-Jadassohn syndrome, dermatopathia pigmentosa reticularis, epidermolysis bullosa simplex 1B, generalized intermediate, epidermolysis bullosa simplex 2F, with mottled pigmentation, epidermolysis bullosa simplex 1C, localized, epidermolysis bullosa simplex 1A, generalized severe, epidermolysis bullosa simplex.

BP4

Computational evidence support a benign effect (MetaRNN=0.15579712).
