Genes affected

GARS1 (HGNC:4162): (glycyl-tRNA synthetase 1) This gene encodes glycyl-tRNA synthetase, one of the aminoacyl-tRNA synthetases that charge tRNAs with their cognate amino acids. The encoded enzyme is an (alpha)2 dimer which belongs to the class II family of tRNA synthetases. It has been shown to be a target of autoantibodies in the human autoimmune diseases, polymyositis or dermatomyositis. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Oct 2015]

GARS1-DT (HGNC:48951): (GARS1 divergent transcript)

ACMG classification

Verdict is Benign. Variant got -9 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.057976395).
• BP6: Variant 7-30595016-T-C is Benign according to our data. Variant chr7-30595016-T-C is described in ClinVar as [Benign]. Clinvar id is 217861.Status of the report is no_assertion_criteria_provided, 0 stars.
• BS2: High AC in GnomAdExome4 at 10 AD gene.
