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]

Anauxetic dysplasia Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Apr 06, 2022 | This variant occurs in the RMRP gene, which encodes an RNA molecule that does not result in a protein product. This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with RMRP-related conditions. ClinVar contains an entry for this variant (Variation ID: 533764). Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. - |
