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]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -11 ACMG points.

PM1
In a hotspot region, there are 3 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 6 uncertain in NM_002047.4
PP3
Multiple lines of computational evidence support a deleterious effect 9: AlphaMissense, BayesDel_noAF, Cadd, Eigen, FATHMM_MKL, phyloP100way_vertebrate, PROVEAN, REVEL, REVEL [when BayesDel_addAF, max_spliceai, MetaRNN, MutationTaster was below the threshold]
BP4
Computational evidence support a benign effect (MetaRNN=0.057784617).
BP6
Variant 7-30628584-T-C is Benign according to our data. Variant chr7-30628584-T-C is described in ClinVar as [Benign]. Clinvar id is 416089.Status of the report is criteria_provided_single_submitter, 1 stars.
BS1
Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.000643 (98/152366) while in subpopulation NFE AF = 0.00025 (17/68030). AF 95% confidence interval is 0.000159. There are 1 homozygotes in GnomAd4. There are 71 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
BS2
High AC in GnomAd4 at 98 AD gene.
