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 Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Labcorp Genetics (formerly Invitae), Labcorp | May 17, 2023 | For these reasons, this variant has been classified as Pathogenic. Studies have shown that this variant alters RMRP gene expression (PMID: 14608646). ClinVar contains an entry for this variant (Variation ID: 14219). This variant is also known as -20ins17. This variant has been observed in individuals with cartilage-hair hypoplasia-anauxetic dysplasia (CHH-AD) spectrum disorders (PMID: 14608646). 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 not present in population databases (gnomAD no frequency). This variant occurs in the RMRP gene, which encodes an RNA molecule that does not result in a protein product. - |
