Genes affected
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]

Uncertain significance, criteria provided, single submitter | clinical testing | Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine | Jun 23, 2015 | The p.Gly622Ser variant in TSPEAR has not been previously reported in individual s with hearing loss and data from large population studies is insufficient to as sess the frequency of this variant. Computational prediction tools and conservat ion analyses do not provide strong support for or against an impact to the prote in. In summary, the clinical significance of the p.Gly622Ser variant is uncertai n. - |
