Genes affected
KRTAP10-9 (HGNC:22971): (keratin associated protein 10-9) 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 GeneticsDec 17, 2023The c.283T>G (p.C95G) alteration is located in exon 1 (coding exon 1) of the KRTAP10-9 gene. This alteration results from a T to G substitution at nucleotide position 283, causing the cysteine (C) at amino acid position 95 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
