Genes affected
TMEM126B (HGNC:30883): (transmembrane protein 126B) This gene encodes a mitochondrial transmembrane protein which is a component of the mitochondrial complex I assembly complex. The encoded protein serves as an assembly factor that is required for formation of the membrane arm of the complex. It interacts with NADH dehydrogenase [ubiquinone] 1 alpha subcomplex assembly factor 13. Naturally occurring mutations in this gene are associated with isolated complex I deficiency. A pseudogene of this gene has been defined on chromosome 9. [provided by RefSeq, Apr 2017]

Pathogenic, criteria provided, single submitter | clinical testing | Labcorp Genetics (formerly Invitae), Labcorp | Jul 15, 2022 | For these reasons, this variant has been classified as Pathogenic. This variant has not been reported in the literature in individuals affected with TMEM126B-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Tyr63Ilefs*6) in the TMEM126B gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in TMEM126B are known to be pathogenic (PMID: 27374774). - |
