Genes affected

KRTAP10-6 (HGNC:20523): (keratin associated protein 10-6) Predicted to be located in cytosol. [provided by Alliance of Genome Resources, Apr 2022]

KRTAP10-6 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]

The c.105C>A (p.D35E) alteration is located in exon 1 (coding exon 1) of the KRTAP10-6 gene. This alteration results from a C to A substitution at nucleotide position 105, causing the aspartic acid (D) at amino acid position 35 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
