Genes affected

LARS2 (HGNC:17095): (leucyl-tRNA synthetase 2, mitochondrial) This gene encodes a class 1 aminoacyl-tRNA synthetase, mitochondrial leucyl-tRNA synthetase. Each of the twenty aminoacyl-tRNA synthetases catalyzes the aminoacylation of a specific tRNA or tRNA isoaccepting family with the cognate amino acid. [provided by RefSeq, Jul 2008]

LARS2-AS1 (HGNC:40796): (LARS2 antisense RNA 1)

ACMG classification

Our verdict: Benign. The variant received -21 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.88).
• BP6: Variant 3-45491732-G-A is Benign according to our data. Variant chr3-45491732-G-A is described in ClinVar as Benign. ClinVar VariationId is 226693.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BP7: Synonymous conserved (PhyloP=-3.83 with no splicing effect.
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.953 is higher than 0.05.
