Genes affected
KRT6C (HGNC:20406): (keratin 6C) 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, Jul 2009]

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 01, 2023The c.1604T>C (p.I535T) alteration is located in exon 9 (coding exon 9) of the KRT6C gene. This alteration results from a T to C substitution at nucleotide position 1604, causing the isoleucine (I) at amino acid position 535 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
