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 GeneticsFeb 16, 2023The c.1326G>T (p.Q442H) alteration is located in exon 7 (coding exon 7) of the KRT36 gene. This alteration results from a G to T substitution at nucleotide position 1326, causing the glutamine (Q) at amino acid position 442 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
