Genes affected

KRT36 (HGNC:6454): (keratin 36) The protein encoded by this gene is a member of the keratin gene family. This type I hair keratin is an acidic protein which heterodimerizes with type II keratins to form hair and nails. The type I hair keratins are clustered in a region of chromosome 17q12-q21 and have the same direction of transcription. [provided by RefSeq, Jul 2008]

Ambry Genetics

Dec 21, 2023

The c.940C>T (p.R314C) alteration is located in exon 5 (coding exon 5) of the KRT36 gene. This alteration results from a C to T substitution at nucleotide position 940, causing the arginine (R) at amino acid position 314 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
