Genes affected

D2HGDH (HGNC:28358): (D-2-hydroxyglutarate dehydrogenase) This gene encodes D-2hydroxyglutarate dehydrogenase, a mitochondrial enzyme belonging to the FAD-binding oxidoreductase/transferase type 4 family. This enzyme, which is most active in liver and kidney but also active in heart and brain, converts D-2-hydroxyglutarate to 2-ketoglutarate. Mutations in this gene are present in D-2-hydroxyglutaric aciduria, a rare recessive neurometabolic disorder causing developmental delay, epilepsy, hypotonia, and dysmorphic features.

The c.1267G>A (p.G423S) alteration is located in exon 9 (coding exon 8) of the D2HGDH gene. This alteration results from a G to A substitution at nucleotide position 1267, causing the glycine (G) at amino acid position 423 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
