Genes affected
MAOB (HGNC:6834): (monoamine oxidase B) The protein encoded by this gene belongs to the flavin monoamine oxidase family. It is a enzyme located in the mitochondrial outer membrane. It catalyzes the oxidative deamination of biogenic and xenobiotic amines and plays an important role in the metabolism of neuroactive and vasoactive amines in the central nervous sysytem and peripheral tissues. This protein preferentially degrades benzylamine and phenylethylamine. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 24, 2024The c.1514C>T (p.T505M) alteration is located in exon 15 (coding exon 15) of the MAOB gene. This alteration results from a C to T substitution at nucleotide position 1514, causing the threonine (T) at amino acid position 505 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
