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]

The c.10T>G (p.F4V) alteration is located in exon 1 (coding exon 1) of the TMEM126B gene. This alteration results from a T to G substitution at nucleotide position 10, causing the phenylalanine (F) at amino acid position 4 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
