Genes affected
HARS1 (HGNC:4816): (histidyl-tRNA synthetase 1) Aminoacyl-tRNA synthetases are a class of enzymes that charge tRNAs with their cognate amino acids. The protein encoded by this gene is a cytoplasmic enzyme which belongs to the class II family of aminoacyl-tRNA synthetases. The enzyme is responsible for the synthesis of histidyl-transfer RNA, which is essential for the incorporation of histidine into proteins. The gene is located in a head-to-head orientation with HARSL on chromosome five, where the homologous genes share a bidirectional promoter. The gene product is a frequent target of autoantibodies in the human autoimmune disease polymyositis/dermatomyositis. Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Apr 2012]
WDR55 (HGNC:25971): (WD repeat domain 55) Predicted to be involved in rRNA processing. Located in nucleolus and nucleoplasm. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -1 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.3).
BS1
Variant frequency is greater than expected in population nfe. gnomad4_exome allele frequency = 0.0000863 (35/405430) while in subpopulation NFE AF= 0.000135 (33/243700). AF 95% confidence interval is 0.0000988. There are 0 homozygotes in gnomad4_exome. There are 18 alleles in male gnomad4_exome subpopulation. Median coverage is 0. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
