Subsequent screening of a PMD cohort without a genetic diagnosis identified an unrelated individual with novel compound heterozygous variants including a missense variant c.[1367C>T] p.(Ser456Leu) and a de novo deletion c.[1846_1847delTA] p.(Tyr616Leufs*6).
Whole-exome sequencing in two siblings presenting with clinical symptoms of PMD revealed a homozygous variant in the arginyl-tRNA synthetase (RARS) gene: NM_002887.3: c.[5A>G] p.(Asp2Gly).
We found significant associations with the risk of breast cancer for rs34087264 in AARS [odds ratio (OR) = 1.15, 95% confidence interval (CI) = 1.01-1.31], rs801186 in HARS (OR = 1.29, 95% CI = 1.08-1.54), rs193466 in RARS (OR = 1.17, 95% CI = 1.02-1.35), and rs2273802 in WARS (OR = 1.14, 95% CI = 1.01-1.30).
