Comment on list classification: This gene has been demoted to Amber until further evidence is provided. This gene is currently Red on the Mitochondrial disorders panel (code 112, Version 1.141) - further evidence needs to be submitted to support promoting this gene family member to Green.Created: 29 Mar 2019, 1:49 p.m.
Comment on list classification: Single case in the literature therefore this should be a red gene - PMID: 26741492 describes the finding of a 500kb region of homozygosity encompassing the MRPS23 gene within a boy with hepatic disease and combined respiratpry chain complex deficiencies. The patient was homozygous for the candidate variant c.119C>G p.P40R (both parents were heterozygous). In vitro complementation assays resuced defects in complexes I and IV, and restored motochondrial 12S rRNA/16S rRNA expression.Created: 15 Feb 2016, 2:40 p.m.
