Genes affected
KARS1 (HGNC:6215): (lysyl-tRNA synthetase 1) Aminoacyl-tRNA synthetases are a class of enzymes that charge tRNAs with their cognate amino acids. Lysyl-tRNA synthetase is a homodimer localized to the cytoplasm which belongs to the class II family of tRNA synthetases. It has been shown to be a target of autoantibodies in the human autoimmune diseases, polymyositis or dermatomyositis. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

Uncertain significance, criteria provided, single submitter | clinical testing | Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine | Sep 29, 2017 | The p.Pro328Ser variant in KARS has not been previously reported in individuals with hearing loss or in large population studies. Computational prediction tools and conservation analysis suggest that the p.Pro328Ser variant may impact the p rotein, though this information is not predictive enough to determine pathogenic ity. In summary, the clinical significance of the p.Pro328Ser variant is uncerta in. ACMG/AMP Criteria applied: PM2, PP3 (Richards 2015). - |
