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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 07, 2023The c.584G>A (p.S195N) alteration is located in exon 3 (coding exon 3) of the KRT38 gene. This alteration results from a G to A substitution at nucleotide position 584, causing the serine (S) at amino acid position 195 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
