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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 27, 2024The c.490C>T (p.R164W) alteration is located in exon 1 (coding exon 1) of the KRT15 gene. This alteration results from a C to T substitution at nucleotide position 490, causing the arginine (R) at amino acid position 164 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
