Genes affected

KRT34 (HGNC:6452): (keratin 34) The protein encoded by this gene is a member of the keratin gene family. As a type I hair keratin, it 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 01, 2022

The c.1111C>T (p.R371C) alteration is located in exon 6 (coding exon 6) of the KRT34 gene. This alteration results from a C to T substitution at nucleotide position 1111, causing the arginine (R) at amino acid position 371 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
