Genes affected

KRTAP10-4 (HGNC:20521): (keratin associated protein 10-4) This is an intronless gene located in a cluster of related genes on the q arm of chromosome 21. The proteins encoded by these genes form disulfide bonds with cysteine residues in hair keratins, thereby contributing to the structure and stability of hair fibers. [provided by RefSeq, Apr 2014]

KRTAP10-4 links:

TSPEAR (HGNC:1268): (thrombospondin type laminin G domain and EAR repeats) This gene encodes a protein that contains a N-terminal thrombospondin-type laminin G domain and several tandem arranged epilepsy-associated repeats (EARs). A mutation in this gene is the cause of autosomal recessive deafness-98. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Dec 2012]

Collection Method:clinical testing

The c.125G>A (p.C42Y) alteration is located in exon 1 (coding exon 1) of the KRTAP10-4 gene. This alteration results from a G to A substitution at nucleotide position 125, causing the cysteine (C) at amino acid position 42 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
