Genes affected
DAO (HGNC:2671): (D-amino acid oxidase) This gene encodes the peroxisomal enzyme D-amino acid oxidase. The enzyme is a flavoprotein which uses flavin adenine dinucleotide (FAD) as its prosthetic group. Its substrates include a wide variety of D-amino acids, but it is inactive on the naturally occurring L-amino acids. Its biological function is not known; it may act as a detoxifying agent which removes D-amino acids that accumulate during aging. In mice, it degrades D-serine, a co-agonist of the NMDA receptor. This gene may play a role in the pathophysiology of schizophrenia. [provided by RefSeq, Jul 2008]

DAO-related disorder Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingPreventionGenetics, part of Exact SciencesMar 20, 2023The DAO c.113G>A variant is predicted to result in the amino acid substitution p.Arg38His. This variant was reported in an individual with amyotrophic lateral sclerosis; however, this individual also had a C9orf72 repeat expansion. Therefore, this variant was suggested to be a rare polymorphism (Millecamps et al. 2010. PubMed ID: 20538972; Millecamps et al. 2012. PubMed ID: 22499346). This variant is reported in 0.014% of alleles in individuals of European (Non-Finnish) descent in gnomAD (http://gnomad.broadinstitute.org/variant/12-109278895-G-A). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
