Variant summary

Our verdict is Uncertain significance. The variant received 3 ACMG points: 3P and 0B. PM5PP2

The NM_001040436.3(YARS2):c.1106G>C(p.Cys369Ser) variant causes a missense, splice region change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000496 in 1,613,878 control chromosomes in the GnomAD database, with no homozygous occurrence. 1/1 splice prediction tools predict no significant impact on normal splicing. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another nucleotide change resulting in the same amino acid substitution has been previously reported as Uncertain significance in ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. C369Y) has been classified as Pathogenic.

Genes affected

YARS2 (HGNC:24249): (tyrosyl-tRNA synthetase 2) This gene encodes a mitochondrial protein that catalyzes the attachment of tyrosine to tRNA(Tyr). Mutations in this gene are associated with myopathy with lactic acidosis and sideroblastic anemia type 2 (MLASA2). [provided by RefSeq, Jan 2011]

ACMG classification

Classification was made for transcript

Our verdict: Uncertain_significance. The variant received 3 ACMG points.

PM5

Other missense variant is known to change same aminoacid residue: Variant chr12-32750105-C-T is described in ClinVar as Pathogenic. ClinVar VariationId is 426098.Status of the report is no_assertion_criteria_provided, 0 stars.

PP2

Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 13 curated pathogenic missense variants (we use a threshold of 10). The gene has 3 curated benign missense variants. Gene score misZ: 0.26421 (below the threshold of 3.09). Trascript score misZ: 0.56393 (below the threshold of 3.09). GenCC associations: The gene is linked to myopathy, lactic acidosis, and sideroblastic anemia, myopathy, lactic acidosis, and sideroblastic anemia 2.
