Genes affected

ENO1 (HGNC:3350): (enolase 1) This gene encodes alpha-enolase, one of three enolase isoenzymes found in mammals. Each isoenzyme is a homodimer composed of 2 alpha, 2 gamma, or 2 beta subunits, and functions as a glycolytic enzyme. Alpha-enolase in addition, functions as a structural lens protein (tau-crystallin) in the monomeric form. Alternative splicing of this gene results in a shorter isoform that has been shown to bind to the c-myc promoter and function as a tumor suppressor. Several pseudogenes have been identified, including one on the long arm of chromosome 1. Alpha-enolase has also been identified as an autoantigen in Hashimoto encephalopathy.

Ambry Genetics

Apr 25, 2022

The c.874A>G (p.I292V) alteration is located in exon 9 (coding exon 8) of the ENO1 gene. This alteration results from a A to G substitution at nucleotide position 874, causing the isoleucine (I) at amino acid position 292 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
