Genes affected
DDO (HGNC:2727): (D-aspartate oxidase) The protein encoded by this gene is a peroxisomal flavoprotein that catalyzes the oxidative deamination of D-aspartate and N-methyl D-aspartate. Flavin adenine dinucleotide or 6-hydroxyflavin adenine dinucleotide can serve as the cofactor in this reaction. Several transcript variants encoding different isoforms have been found for this gene.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 01, 2022The c.659G>A (p.G220E) alteration is located in exon 5 (coding exon 5) of the DDO gene. This alteration results from a G to A substitution at nucleotide position 659, causing the glycine (G) at amino acid position 220 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
