Summaries for Brunner Syndrome

NIH Rare Diseases : 54 Monoamine oxidase A deficiency is a rare condition that is characterized by mild intellectual disability and behavioral difficulties (including aggressive and sometimes violent behaviors and autistic features). Affected people may also experience night terrors, tremor, stereotypical hand movements, and/or occasional body twitches. Signs and symptoms generally develop in childhood and the condition is seen almost exclusively in males. Monoamine oxidase A deficiency is caused by changes (mutations) in the MAOA gene and is inherited in an X-linked recessive manner. Treatment is based on the signs and symptoms present in each person. Some recent studies suggest that cautious treatment with certain medications (called selective serotonin reuptake inhibitors) and dietary modifications can improve symptoms.

MalaCards based summary : Brunner Syndrome, also known as monoamine oxidase a deficiency, is related to conduct disorder and paranoid schizophrenia. An important gene associated with Brunner Syndrome is MAOA (Monoamine Oxidase A), and among its related pathways/superpathways are Histidine metabolism and Tyrosine metabolism. Related phenotypes are behavioral abnormality and cognitive impairment

Disease Ontology : 12 An amino acid metabolic disorder characterized by recessive X-linked inhetiance, impaired monoamine metabolism, impulsive aggressiveness and mild mental retardation that has material basis in mutation in the MAOA gene on chromosome Xp11.

Genetics Home Reference : 26 Monoamine oxidase A deficiency is a rare disorder that occurs almost exclusively in males. It is characterized by mild intellectual disability and behavioral problems beginning in early childhood.

OMIM : 58 Brunner syndrome is a recessive X-linked disorder characterized by impulsive aggressiveness and mild mental retardation associated with MAOA deficiency (Brunner et al., 1993). (300615)

UniProtKB/Swiss-Prot : 76 Brunner syndrome: A form of X-linked non-dysmorphic mild mental retardation. Male patients are affected by borderline mental retardation and exhibit abnormal behavior, including disturbed regulation of impulsive aggression. Obligate female carriers have normal intelligence and behavior.
