Genes affected

KRT37 (HGNC:6455): (keratin 37) 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.1061G>A (p.R354H) alteration is located in exon 6 (coding exon 6) of the KRT37 gene. This alteration results from a G to A substitution at nucleotide position 1061, causing the arginine (R) at amino acid position 354 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
