Genes affected

KRT35 (HGNC:6453): (keratin 35) 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]

The c.1031C>T (p.T344M) alteration is located in exon 6 (coding exon 6) of the KRT35 gene. This alteration results from a C to T substitution at nucleotide position 1031, causing the threonine (T) at amino acid position 344 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
