Genes affected

ATP5MC3 (HGNC:843): (ATP synthase membrane subunit c locus 3) This gene encodes a subunit of mitochondrial ATP synthase. Mitochondrial ATP synthase catalyzes ATP synthesis, utilizing an electrochemical gradient of protons across the inner membrane during oxidative phosphorylation. ATP synthase is composed of two linked multi-subunit complexes: the soluble catalytic core, F1, and the membrane-spanning component, Fo, comprising the proton channel. The catalytic portion of mitochondrial ATP synthase consists of 5 different subunits (alpha, beta, gamma, delta, and epsilon) assembled with a stoichiometry of 3 alpha, 3 beta, and a single representative of the other 3. The proton channel seems to have nine subunits (a, b, c, d, e, f, g, F6 and 8). This gene is one of three genes that encode subunit c of the proton channel. Each of the three genes have distinct mitochondrial import sequences but encode the identical mature protein. Alternatively spliced transcript variants encoding different proteins have been identified. [provided by RefSeq, Jun 2010]

The c.161A>G (p.Q54R) alteration is located in exon 3 (coding exon 3) of the ATP5G3 gene. This alteration results from an A to G substitution at nucleotide position 161, causing the glutamine (Q) at amino acid position 54 to be replaced by an arginine (R). This allele was reported in one heterozygous individual in population-based cohorts in the Genome Aggregation Database (gnomAD). This amino acid position is well conserved in available vertebrate species. This alteration is predicted to be tolerated by in silico analysis. Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
