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]

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 (rs727502775, gnomAD 0.02%). This variant has been observed in individuals with RMRP-related conditions (PMID: 11207361, 16254002, 28094436). Other insertions and duplications immediately upstream of the coding sequence have been reported in individuals affected with cartilage-hair hypoplasia-anauxetic dysplasia (CHH-AD) spectrum disorders (PMID: 16244706, 11207361, 12107819). This variant is also known as n.-23_-14dup. While functional studies for this variant have not been reported, experimental analyses using patient derived cells, as well as in vitro transfection studies, have shown that promoter insertions result in silencing of RMRP transcription and reduced expression of the gene product (PMID: 11207361, 16254002). For these reasons, this variant has been classified as Pathogenic. -
