Genes affected

KRTAP1-1 (HGNC:16772): (keratin associated protein 1-1) 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 high sulfur KAP family and the gene is localized to a cluster of KAPs at 17q12-q21. [provided by RefSeq, Jul 2008]

Mar 27, 2023

The c.84C>A (p.S28R) alteration is located in exon 1 (coding exon 1) of the KRTAP1-1 gene. This alteration results from a C to A substitution at nucleotide position 84, causing the serine (S) at amino acid position 28 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
