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

The c.578C>T (p.P193L) alteration is located in exon 4 (coding exon 4) of the AIMP2 gene. This alteration results from a C to T substitution at nucleotide position 578, causing the proline (P) at amino acid position 193 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
