Variant summary: RMRP n.176G>A alters a conserved nucleotide in the non-coding RNA. The variant allele was found at a frequency of 0.00082 in 130430 control chromosomes, predominantly at a frequency of 0.0088 within the East Asian subpopulation in the gnomAD database. The observed variant frequency within East Asian control individuals in the gnomAD database is approximately 1.2 fold of the estimated maximal expected allele frequency for a pathogenic variant in RMRP causing Cartilage-Hair Hypoplasia phenotype (0.0072), strongly suggesting that the variant is a benign polymorphism found primarily in populations of East Asian origin. To our knowledge, no occurrence of n.176G>A in individuals affected with Cartilage-Hair Hypoplasia and no experimental evidence demonstrating its impact on protein function have been reported. One clinical diagnostic laboratory has submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation and classified the variant as likely benign. Based on the evidence outlined above, the variant was classified as benign. -
