Genes affected

KRTAP4-7 (HGNC:18898): (keratin associated protein 4-7) This protein is a member of the keratin-associated protein (KAP) family. The KAP proteins form a matrix of keratin intermediate filaments which contribute to the structure of hair fibers. KAP family members appear to have unique, family-specific amino- and carboxyl-terminal regions and are subdivided into three multi-gene families according to amino acid composition: the high sulfur, the ultrahigh sulfur, and the high tyrosine/glycine KAPs. This protein is a member of the ultrahigh sulfur KAP family and the gene is localized to a cluster of KAPs at 17q12-q21. [provided by RefSeq, Mar 2009]

The c.329G>A (p.C110Y) alteration is located in exon 1 (coding exon 1) of the KRTAP4-7 gene. This alteration results from a G to A substitution at nucleotide position 329, causing the cysteine (C) at amino acid position 110 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
