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]
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 GeneticsFeb 17, 2022The c.134C>G (p.P45R) alteration is located in exon 1 (coding exon 1) of the KRTAP10-7 gene. This alteration results from a C to G substitution at nucleotide position 134, causing the proline (P) at amino acid position 45 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
