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]

Ambry Genetics

Sep 20, 2023

The c.910G>A (p.E304K) alteration is located in exon 9 (coding exon 8) of the ME2 gene. This alteration results from a G to A substitution at nucleotide position 910, causing the glutamic acid (E) at amino acid position 304 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
