Genes affected
KRT71 (HGNC:28927): (keratin 71) Keratins are intermediate filament proteins responsible for the structural integrity of epithelial cells and are subdivided into epithelial keratins and hair keratins. This gene encodes a protein that is expressed in the inner root sheath of hair follicles. The type II keratins are clustered in a region of chromosome 12q13.[provided by RefSeq, Jun 2009]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 11, 2021The c.1460T>A (p.V487E) alteration is located in exon 9 (coding exon 9) of the KRT71 gene. This alteration results from a T to A substitution at nucleotide position 1460, causing the valine (V) at amino acid position 487 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
