Genes affected
KRT35 (HGNC:6453): (keratin 35) 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 GeneticsNov 23, 2024The c.767C>T (p.A256V) alteration is located in exon 4 (coding exon 4) of the KRT35 gene. This alteration results from a C to T substitution at nucleotide position 767, causing the alanine (A) at amino acid position 256 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
