Genes affected
KRTAP10-10 (HGNC:22972): (keratin associated protein 10-10) Predicted to be located in cytosol. [provided by Alliance of Genome Resources, Apr 2022]
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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 07, 2024The c.167C>T (p.A56V) alteration is located in exon 1 (coding exon 1) of the KRTAP10-10 gene. This alteration results from a C to T substitution at nucleotide position 167, causing the alanine (A) at amino acid position 56 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
