Genes affected
KRT75 (HGNC:24431): (keratin 75) This gene is a member of the type II keratin family clustered on the long arm of chromosome 12. Type I and type II keratins heteropolymerize to form intermediate-sized filaments in the cytoplasm of epithelial cells. This gene is expressed in the companion layer, upper germinative matrix region of the hair follicle, and medulla of the hair shaft. The encoded protein plays an essential role in hair and nail formation. Variations in this gene have been associated with the hair disorders pseudofolliculitis barbae (PFB) and loose anagen hair syndrome (LAHS). [provided by RefSeq, Oct 2008]

Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Jun 24, 2022 | The c.1328C>T (p.A443V) alteration is located in exon 7 (coding exon 7) of the KRT75 gene. This alteration results from a C to T substitution at nucleotide position 1328, causing the alanine (A) at amino acid position 443 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
