Genes affected

RMND1 (HGNC:21176): (required for meiotic nuclear division 1 homolog) The protein encoded by this gene belongs to the evolutionary conserved sif2 family of proteins that share the DUF155 domain in common. This protein is thought to be localized in the mitochondria and involved in mitochondrial translation. Mutations in this gene are associated with combined oxidative phosphorylation deficiency-11. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Dec 2012]

Pathogenic, criteria provided, single submitter	clinical testing	Lifecell International Pvt. Ltd	-	A Homozygote Stop readthrough variant c.1349G>C in Exon 12 of the RMND1 gene that results in the amino acid substitution p.Ter450Serext*? was identified. The observed variant has a minor allele frequency of 0.00002% in gnomAD exomes and novel is gnomAD genomes, respectively. The severity of the impact of this variant on the protein is medium, based on the effect of the protein and REVEL score. Rare Exome Variant Ensemble Learner (REVEL) is an ensembl method for predicting the pathogenicity of missense variants based on a combination of scores from 13 individual tools: MutPred, FATHMM v2.3, VEST 3.0, PolyPhen-2, SIFT, PROVEAN, MutationAssessor, MutationTaster, LRT, GERP++, SiPhy, phyloP, and phastCons. The REVEL score for an individual missense variant can range from 0 to 1, with higher scores reflecting greater likelihood that the variant is disease-causing. ClinVar has also classified this variant as Pathogenic [Variation ID: 143051]. The observed variation has been reported in mitochondrial disorders patients (Vinu N, et.al, 2018). For these reasons, this variant has been classified as Pathogenic. -
