Variant summary

Our verdict is Uncertain significance. The variant received 0 ACMG points: 2P and 2B. PM2BP4_Moderate

The NM_152335.5(TMEM266):c.826C>A(p.Pro276Thr) variant causes a missense change. The variant allele was found at a frequency of 0.00000844 in 1,539,420 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. P276A) has been classified as Uncertain significance.

Genes affected

TMEM266 (HGNC:26763): (transmembrane protein 266) Enables protein homodimerization activity. Predicted to be involved in transmembrane transport. Located in cytosol; dendrite; and plasma membrane. Is integral component of plasma membrane. [provided by Alliance of Genome Resources, Apr 2022]

TMEM266 links:

ETFA (HGNC:3481): (electron transfer flavoprotein subunit alpha) ETFA participates in catalyzing the initial step of the mitochondrial fatty acid beta-oxidation. It shuttles electrons between primary flavoprotein dehydrogenases and the membrane-bound electron transfer flavoprotein ubiquinone oxidoreductase. Defects in electron-transfer-flavoprotein have been implicated in type II glutaricaciduria in which multiple acyl-CoA dehydrogenase deficiencies result in large excretion of glutaric, lactic, ethylmalonic, butyric, isobutyric, 2-methyl-butyric, and isovaleric acids. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]
