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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 29, 2023The c.717G>T (p.K239N) alteration is located in exon 8 (coding exon 7) of the ENO2 gene. This alteration results from a G to T substitution at nucleotide position 717, causing the lysine (K) at amino acid position 239 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
