Genes affected
KRT36 (HGNC:6454): (keratin 36) 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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 26, 2023The c.795G>C (p.M265I) alteration is located in exon 4 (coding exon 4) of the KRT36 gene. This alteration results from a G to C substitution at nucleotide position 795, causing the methionine (M) at amino acid position 265 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
