Genes affected

KRTAP10-12 (HGNC:20533): (keratin associated protein 10-12) Predicted to be located in cytosol. [provided by Alliance of Genome Resources, Apr 2022]

KRTAP10-12 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]

Ambry Genetics

Jul 15, 2021

The c.127G>A (p.A43T) alteration is located in exon 1 (coding exon 1) of the KRTAP10-12 gene. This alteration results from a G to A substitution at nucleotide position 127, causing the alanine (A) at amino acid position 43 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
