Genes affected

AIMP2 (HGNC:20609): (aminoacyl tRNA synthetase complex interacting multifunctional protein 2) The protein encoded by this gene is part of the aminoacyl-tRNA synthetase complex, which contains nine different aminoacyl-tRNA synthetases and three non-enzymatic factors. The encoded protein is one of the non-enzymatic factors and is required for assembly and stability of the complex. [provided by RefSeq, May 2016]

AIMP2 links:

EIF2AK1 (HGNC:24921): (eukaryotic translation initiation factor 2 alpha kinase 1) The protein encoded by this gene acts at the level of translation initiation to downregulate protein synthesis in response to stress. The encoded protein is a kinase that can be inactivated by hemin. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Aug 2008]

Collection Method: clinical testing

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. An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant¬†is likely to be tolerated. ClinVar contains an entry for this variant (Variation ID: 1948769). This variant has not been reported in the literature in individuals affected with AIMP2-related conditions. This variant is present in population databases (rs369386259, gnomAD 0.03%). This sequence change replaces histidine, which is basic and polar, with aspartic acid, which is acidic and polar, at codon 225 of the AIMP2 protein (p.His225Asp). -
