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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 04, 2024The c.991G>A (p.A331T) alteration is located in exon 9 (coding exon 8) of the ENO2 gene. This alteration results from a G to A substitution at nucleotide position 991, causing the alanine (A) at amino acid position 331 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
