Genes affected

ENO2 (HGNC:3353): (enolase 2) This gene encodes one of the three enolase isoenzymes found in mammals. This isoenzyme, a homodimer, is found in mature neurons and cells of neuronal origin. A switch from alpha enolase to gamma enolase occurs in neural tissue during development in rats and primates. [provided by RefSeq, Jul 2008]

Feb 13, 2024

The c.548G>A (p.R183Q) alteration is located in exon 7 (coding exon 6) of the ENO2 gene. This alteration results from a G to A substitution at nucleotide position 548, causing the arginine (R) at amino acid position 183 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
