monoamine oxidase a gene polymorphisms and bipolar disorder in iranian population

Monoamine Oxidase A Gene Polymorphisms and Bipolar Disorder in Iranian Population

BACKGROUND Bipolar disorder (BPD) is a common and severe mood disorder. Although genetic factors have important rolesin the etiology of bipolar disorder, no specific gene has been identified in relation to this disorder. Monoamine oxidase gene is suggested to be associated with bipolar disorder in many studies. OBJECTIVES This study aimed to investigatethe role of MAOA gene polymorphisms in t...

A functional polymorphism in the promoter of monoamine oxidase A gene and bipolar affective disorder.

The genes encoding for the enzymes monoamine oxidase (MAO) A and B are good candidates to investigate bipolar affective disorder. A 30 bp repeat in the MAOA promoter was recently demonstrated to be polymorphic and to affect transcriptional activity. In a family-based association design we found that none of the different repeat copies was preferentially transmitted from mothers (n = 131) to the...

association of monoamine oxidase b and catechol-o-methyltransferase polymorphisms with sporadic parkinson’s disease in an iranian population

Association of monoamine oxidase B and catechol-O-methyltransferase polymorphisms with sporadic Parkinson's disease in an Iranian population.

Genetic polymorphisms have been shown to be involved in dopaminergic neurotransmission. This may influence susceptibility to Parkinson's disease (PD). We performed a case-control study of the association between PD susceptibility and a genetic polymorphism of MAOB and COMT, both separately and in combination, in Iranians. The study enrolled 103 Iranian patients with PD and 70 healthy individual...

Association of Two Polymorphisms in H2B.W Gene with Azoospermia and Severe Oligozoospermia in An Iranian Population

Background During spermatogenesis, the H2B family, member W (H2B.W) gene, encodes a testis specific histone that is co-localized with telomeric sequences and has the potential role to mediate the sperm-specific chromatin remodeling. Previously H2B.W genetic variants were reported to be involved in susceptibility to spermatogenesis impairment. In the present study, two single nucleotide polymorp...

Allele Frequency of CYP2C19 Gene Polymorphisms in a Healthy Iranian Population

Cytochrome P450 2C19 (CYP2C19) plays an important role in the metabolism and elimination of a wide range of medications. The polymorphisms of this enzyme give rise to substantial inter-individual and inter-ethnic variability in drug excretion rates and final serum concentrations. For this reason, therapeutic re-sponses and adverse drug reactions may vary from one person to another. In this stud...
