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]
