Genes affected

KRT38 (HGNC:6456): (keratin 38) 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]

The c.1328G>C (p.C443S) alteration is located in exon 7 (coding exon 7) of the KRT38 gene. This alteration results from a G to C substitution at nucleotide position 1328, causing the cysteine (C) at amino acid position 443 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
