Genes affected

KRTAP10-7 (HGNC:22970): (keratin associated protein 10-7) Enables identical protein binding activity. Predicted to be located in cytosol. [provided by Alliance of Genome Resources, Apr 2022]

KRTAP10-7 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.955C>T (p.P319S) alteration is located in exon 1 (coding exon 1) of the KRTAP10-7 gene. This alteration results from a C to T substitution at nucleotide position 955, causing the proline (P) at amino acid position 319 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
