Genes affected
ATP5MGL (HGNC:13213): (ATP synthase membrane subunit g like) Predicted to enable proton transmembrane transporter activity. Predicted to be involved in ATP synthesis coupled proton transport. Located in mitochondrion. [provided by Alliance of Genome Resources, Apr 2022]
CYB5R3 (HGNC:2873): (cytochrome b5 reductase 3) This gene encodes cytochrome b5 reductase, which includes a membrane-bound form in somatic cells (anchored in the endoplasmic reticulum, mitochondrial and other membranes) and a soluble form in erythrocytes. The membrane-bound form exists mainly on the cytoplasmic side of the endoplasmic reticulum and functions in desaturation and elongation of fatty acids, in cholesterol biosynthesis, and in drug metabolism. The erythrocyte form is located in a soluble fraction of circulating erythrocytes and is involved in methemoglobin reduction. The membrane-bound form has both membrane-binding and catalytic domains, while the soluble form has only the catalytic domain. Alternate splicing results in multiple transcript variants. Mutations in this gene cause methemoglobinemias. [provided by RefSeq, Jan 2010]

The c.217G>A (p.A73T) alteration is located in exon 1 (coding exon 1) of the ATP5L2 gene. This alteration results from a G to A substitution at nucleotide position 217, causing the alanine (A) at amino acid position 73 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
