RMRP

Chr 9AR

RNA component of mitochondrial RNA processing endoribonuclease

Also known as: CHH, NME1, RMRPR, RRP2

This gene encodes the RNA component of mitochondrial RNA processing endoribonuclease, which cleaves mitochondrial RNA at DNA replication priming sites and also forms a ribonucleoprotein complex with telomerase that produces double-stranded RNAs processed into small interfering RNAs. Mutations cause cartilage-hair hypoplasia, anauxetic dysplasia, and metaphyseal dysplasia without hypotrichosis, all involving skeletal dysplasia with variable hair abnormalities. Inheritance is autosomal recessive.
