Genes affected
KRT32 (HGNC:6449): (keratin 32) 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 GeneticsSep 07, 2022The c.1117G>C (p.E373Q) alteration is located in exon 6 (coding exon 6) of the KRT32 gene. This alteration results from a G to C substitution at nucleotide position 1117, causing the glutamic acid (E) at amino acid position 373 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
