Genes affected

ME2 (HGNC:6984): (malic enzyme 2) This gene encodes a mitochondrial NAD-dependent malic enzyme, a homotetrameric protein, that catalyzes the oxidative decarboxylation of malate to pyruvate. It had previously been weakly linked to a syndrome known as Friedreich ataxia that has since been shown to be the result of mutation in a completely different gene. Certain single-nucleotide polymorphism haplotypes of this gene have been shown to increase the risk for idiopathic generalized epilepsy. Alternatively spliced transcript variants encoding different isoforms found for this gene. [provided by RefSeq, Dec 2009]

May 08, 2024

The c.475G>A (p.V159I) alteration is located in exon 6 (coding exon 5) of the ME2 gene. This alteration results from a G to A substitution at nucleotide position 475, causing the valine (V) at amino acid position 159 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
