Variant summary

Our verdict is Uncertain significance. The variant received 1 ACMG points: 1P and 0B. PP5

The ENST00000363046.2(RMRP):​n.-1_1insAAGCTGAGGACGAAGCTGAGGACG variant causes a upstream gene change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. It is difficult to determine the true allele frequency of this variant because it is of type INS_BIG, and the frequency of such variant types in population databases may be underestimated and unreliable. Variant has been reported in ClinVar as Pathogenic (no stars).

Genes affected

RMRP (HGNC:10031): (RNA component of mitochondrial RNA processing endoribonuclease) This gene encodes the RNA component of mitochondrial RNA processing endoribonuclease, which cleaves mitochondrial RNA at a priming site of mitochondrial DNA replication. This RNA also interacts with the telomerase reverse transcriptase catalytic subunit to form a distinct ribonucleoprotein complex that has RNA-dependent RNA polymerase activity and produces double-stranded RNAs that can be processed into small interfering RNA. Mutations in this gene are associated with cartilage-hair hypoplasia.[provided by RefSeq, Mar 2010]
