Genes affected
KRTAP10-11 (HGNC:20528): (keratin associated protein 10-11) 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 GeneticsJun 06, 2023The c.22G>A (p.V8I) alteration is located in exon 1 (coding exon 1) of the KRTAP10-11 gene. This alteration results from a G to A substitution at nucleotide position 22, causing the valine (V) at amino acid position 8 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
