Abstract

Objective: The serotonin transporter (5-HTT) gene is considered to be the promising candidate for genetic involvement in psychiatric disorders ovving to its role in the regulation of serotoninergic neurotransmission This gene shovvs genetic polymorphism in this study, the relationship between the frequency of the different alleles of the 5-HTTLPR variant of the 5-HTT gene and the severity of the clinical symptoms of schizpphrenic patients was investigated. Method: We studied the 5-HTTLPR variant of the 5-HTT gene in 243 subjects of whom 122 were unrelated and strictly met DSM-IV criteria for schizophrenia and 121 were healthy and unrelated controls. Severity of the clinical symptoms of the schizophrenic patients was assessed by attending psychiatrists with respect to their hospitalization rates. The variations of the 5-HTTLPR were analyzed by polymerase chain reaction amplification of high molecular weight chromosomal DNA. Results: The analysis of genotype distributior, for 5-HTTLPR polymorphism showed no significant differences betvveen schizophrenia patient and healthy controls. in addition there was no relationship betvveen clinical subgroups, hospitalization rates, duration of illness and 5- HTTLPR polymorphism. Conclusion: Our findings indicated that the 5-HTTLPR variant of the 5-HTT gene seemed not to be a susceptibility factor for schizophrenia. in addition, there vvas no relationship betvveen clinical symptomatology and prognosis and 5-HTTLPR polymorphism.

Özet

Amaç: Serotonin taşıyıcı (5-HTT) gen, polimorfik yapıda bir gen olup serotoninin taşınmasındaki rolü nedeniyle psikiyatrik bozuklukların etyolojisinde önemli bir rol oynadığı öne sürülmektedir. Bu çalışmada şizofreni hastalarında (5-HTT) geninin transkripsiyonel kontrol bölgesindeki (5-HTT gene-linked polymorphic region) (5-HTTLPR) varyantının polimorfizmi ile şizofreniye yatkınlık ve hastalığın klinik alt grupları arasındaki ilişki araştırılmıştır. Yöntem: Çalışmaya, 122 şizofreni tanısı konmuş hasta ve 121 sağlıklı gönüllü kontrol alınmıştır. Şizofren tanısı DSM-IV kriterlerine göre konulmuştur. 5-HTT gen polimorfizmi, çalışma grubundan alınan periferik kan lökositlerden elde edilen DNA'larda polimeraz zincir reaksiyonu tekniği kullanılarak yapılmıştır. Bulgular: Genotip ve allel dağılımı şizofreni ve kontrol grubu arasında 5-HTT genini 5-HTTLPR varyantı bakımından anlamlı bir farklılık bulunmadı. Ayrıca hasta grubunda 5-HTT geninin 5-HTTLPR varyantı ile hastaların hastaneye yatış sıklıkları, hastalığın klinik alt tipi ve süresi arasında anlamlı bir ilişki bulunmamıştır. Sonuç: Bu bulgularımız 5-HTT geninin 5-HTTLPR varyantının şizofreniye yatkınlık oluşturmada önemli bir rol oynamadığını düşündürmektedir. Ayrıca 5-HTT geninin polimorfizmi ile, şizofreninin kliniği ve alt tipleri ile arasında bir ilişki tespit edilememiştir.
