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]

The observed stop gained variant c.105C>A(p.Tyr35Ter) in AIMP2 gene has been reported previously in homozygous state in three individuals, of which two belong to same family with progressive neurodevelopmental disorder (Shukla A, et al., 2018). This variant is reported with 0.004% allele frequency in gnomAD Exomes. It has been submitted to ClinVar with varying interpretations as Uncertain Significance/ Likely Pathogenic/ Pathogenic. The nucleotide change c.105C>A in AIMP2 is predicted as conserved by GERP++ and PhyloP across 100 vertebrates. Computational evidence (MutationTaster - Disease causing) predicts damaging effect on protein structure and function for this variant. This variant is predicted to cause loss of normal protein function through protein truncation. Loss of function variants have been previously reported to be disease causing. For these reasons, this variant has been classified as Likely Pathogenic. -
