Genes affected

AIMP1 (HGNC:10648): (aminoacyl tRNA synthetase complex interacting multifunctional protein 1) The protein encoded by this gene is a cytokine that is specifically induced by apoptosis, and it is involved in the control of angiogenesis, inflammation, and wound healing. The release of this cytokine renders the tumor-associated vasculature sensitive to tumor necrosis factor. The precursor protein is identical to the p43 subunit, which is associated with the multi-tRNA synthetase complex, and it modulates aminoacylation activity of tRNA synthetase in normal cells. This protein is also involved in the stimulation of inflammatory responses after proteolytic cleavage in tumor cells. Multiple transcript variants encoding different isoforms have been found for this gene. A pseudogene has been identified on chromosome 20. [provided by RefSeq, Dec 2008]

The c.71A>T (p.Y24F) alteration is located in exon 2 (coding exon 1) of the AIMP1 gene. This alteration results from a A to T substitution at nucleotide position 71, causing the tyrosine (Y) at amino acid position 24 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

This sequence change replaces tyrosine, which is neutral and polar, with phenylalanine, which is neutral and non-polar, at codon 24 of the AIMP1 protein (p.Tyr24Phe). This variant is present in population databases (rs369840696, gnomAD 0.03%). This variant has not been reported in the literature in individuals affected with AIMP1-related conditions. ClinVar contains an entry for this variant (Variation ID: 1431757). An algorithm developed to predict the effect of missense changes on protein structure and function outputs the following: PolyPhen-2: "Benign". The phenylalanine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. 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. -
