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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 28, 2022The c.1129C>T (p.R377W) alteration is located in exon 6 (coding exon 6) of the KRT37 gene. This alteration results from a C to T substitution at nucleotide position 1129, causing the arginine (R) at amino acid position 377 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
