Ivone Leong (Genomics England Curator)

No further cases have been found for this gene; therefore, this gene will remain a red gene until further evidence is available.

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.
