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]

Significance:Pathogenic

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This variant occurs in the RMRP gene, which encodes an RNA molecule that does not result in a protein product. This variant is present in population databases (no rsID available, gnomAD 0.01%). This variant has been observed in individual(s) with cartilage-hair hypoplasia-anauxetic dysplasia spectrum disorders (PMID: 16244706; internal data). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. This variant is also known as g.35C>T or 35C>U. ClinVar contains an entry for this variant (Variation ID: 533761). Studies have shown that this variant alters RMRP gene expression (PMID: 18164267). For these reasons, this variant has been classified as Pathogenic. -
