Genes affected
VARS1 (HGNC:12651): (valyl-tRNA synthetase 1) Aminoacyl-tRNA synthetases catalyze the aminoacylation of tRNA by their cognate amino acid. Because of their central role in linking amino acids with nucleotide triplets contained in tRNAs, aminoacyl-tRNA synthetases are thought to be among the first proteins that appeared in evolution. The protein encoded by this gene belongs to class-I aminoacyl-tRNA synthetase family and is located in the class III region of the major histocompatibility complex. [provided by RefSeq, Jul 2008]

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 4 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
PP2
Missense variant in gene, where missense usually causes diseases (based on misZ statistic), VARS1. . Gene score misZ 2.6849 (greater than the threshold 3.09). Trascript score misZ 3.4812 (greater than threshold 3.09). GenCC has associacion of gene with combined oxidative phosphorylation defect type 20, neurodevelopmental disorder with microcephaly, seizures, and cortical atrophy.
PP3
MetaRNN computational evidence supports a deleterious effect, 0.765
