For patients with suspected Brunner syndrome, sequence analysis is recommended as the first step in mutation identification. For patients in whom mutations are not identified by full gene sequencing, deletion/duplication analysis is appropriate.
- OMIM 309850: Monoamine Oxidase A; MAOA
- OMIM 300615: Brunner Syndrome
- Gunter et al. Behavioral Genetics in Antisocial Spectrum Disorders and Psychopathy: A Review of the Recent Literature. (2010). Behav. Sci. Law 28: 148-173.
- Confirmation of a clinical diagnosis of Brunner syndrome.
- Carrier testing in adults with a family history of Brunner syndrome.

Specimen Collection and Shipping: Refrigerate until time of shipment. Ship sample within 5 days of collection at room temperature with overnight delivery.
Specimen Requirements:OrageneTM Saliva Collection kit (available through EGL) used according to manufacturer instructions.

Sequence analysis is required before deletion/duplication analysis by targeted CGH array. If sequencing is performed outside of EGL Genetics, please submit a copy of the sequencing report with the test requisition.
- Deletion/duplication analysis of the MAOA gene by CGH array is available for those individuals in whom sequence analysis is negative.
- Custom diagnostic mutation analysis (KM) is available to family members if mutations are identified by targeted mutation testing or sequencing analysis.
- Prenatal testing is available only for known familial mutations to individuals who are confirmed carriers of mutations. Please contact the laboratory genetic counselor to discuss appropriate testing prior to collecting a prenatal specimen.
