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

Our verdict: Benign. The variant received -20 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.77).
• BP6: Variant 7-30594697-G-A is Benign according to our data. Variant chr7-30594697-G-A is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 359992.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BS1: Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.00629 (958/152292) while in subpopulation NFE AF = 0.01 (682/68016). AF 95% confidence interval is 0.0094. There are 10 homozygotes in GnomAd4. There are 459 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.
• BS2: High AC in GnomAd4 at 958 AD gene.
