Background And Aims: The contribution of genetic factors to the susceptibility for developing schizophrenia is well established. Several hypotheses have been developed in an attempt to identify the pathophysiological mechanisms in schizophrenia, with several findings implicating an important role for apoptosis. A limited number of studies investigated the effects of polymorphisms in apoptotic genes on the susceptibility to schizophrenia in different ethnic groups, with none involving an Arab population.

The folate-homocystiene metabolic pathway has been shown to be involved in the susceptibility for developing schizophrenia by several studies. In the present study we investigated the role of three common polymorphisms of the folate-homocysteine metabolic pathway in an Arab population from Syria consisting of 85 schizophrenic patients and 126 healthy controls. The studied polymorphisms included the MTHFR C677T and A1298C, and MTRR A66G, all of which result into amino acid changes, and were previously shown to yield decreased enzymatic activity and alter plasma homocysteine concentration.

Background: The Val158Met single nucleotide polymorphism of the COMT gene has been implicated in the aetiology of schizophrenia, although results from different populations have been conflicting.

Aims: The aim of the present study was to investigate possible association between schizophrenia and Val158Met in a novel Arab population from Syria.

Methods And Materials: 71 unrelated schizophrenic subjects (45 men) and 102 unrelated healthy controls (62 men) were recruited to take part in this case- control study.
