Genes affected

AARS1 (HGNC:20): (alanyl-tRNA synthetase 1) The human alanyl-tRNA synthetase (AARS) belongs to a family of tRNA synthases, of the class II enzymes. Class II tRNA synthases evolved early in evolution and are highly conserved. This is reflected by the fact that 498 of the 968-residue polypeptide human AARS shares 41% identity witht the E.coli protein. tRNA synthases are the enzymes that interpret the RNA code and attach specific aminoacids to the tRNAs that contain the cognate trinucleotide anticodons. They consist of a catalytic domain which interacts with the amino acid acceptor-T psi C helix of the tRNA, and a second domain which interacts with the rest of the tRNA structure.

This variant, c.1538_1540del, results in the deletion of 1 amino acid(s) of the AARS protein (p.Lys513del), but otherwise preserves the integrity of the reading frame. This variant is present in population databases (rs762162379, gnomAD 0.006%). This variant has not been reported in the literature in individuals affected with AARS-related conditions. ClinVar contains an entry for this variant (Variation ID: 476733). Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
