Abstract

Background: Suicidal behavior represents a serious public health problem. Studies about twins, adoption, and family conflicts have shown a relationship between genetics and suicide. CB1 receptors are coded by the cannabinoid-1 receptor (CNR1) gene. It has been shown that CNR1 gene polymorphism (1359 G/A) is associated with many neuropsychiatric disorders, including major depression. Objective: Our aim was to study whether there was an association between the polymorphism of the CNB1 receptor and suicide attempts. We compared non-suicidal subjects with suicide-attempt victims to substantiate these findings. Materials and Methods: Peripheral blood samples were drawn from all of the participants and single nucleotide polymorphism (SNP) of the cannabinoid gene (1359 G/A) was analyzed. Results: The study included 115 suicide attempts (parasuicide patients) (mean age 25.6±8.5; 41 males, 74 females) and 69 unrelated healthy subjects (mean age 27.5±10.6; 38 males, 31 females). The genotype distributions were significantly different between the parasuicide and control groups and this difference was attributed to the AG genotype rates (21.7% vs 44.9%, p=0.001). Having the AG genotype lowered the admission to the ED due to parasuicide 3.3 times (95% CI: 1.6-6.8). The frequencies of A and G alleles in the CNR1 gene polymorphism were 16.1% (n=37) and 83.9% (n=193) in parasuicide patients and 22.5% (n=31) and 77.5% (n=107) in the control group, respectively (p=0.127). All the subjects with the AA genotype were in the parasuicide group (n=6). The frequency of the AG genotype was significantly lower in parasuicide patients with a previous psychiatric diagnosis compared to suicide attempts without a previous diagnosis (32% (n=8) vs. 68% (n=17); p=0.004). Conclusion: There is a preventive association between CNR1 rs1049353 (1359 G/A) gene polymorphism and parasuicide patients. CNR1 receptor polymorphism may be used as a biological test to help predict and prevent suicidal behavior if the relationship can be proved with further studies.

Özet

Giriş: İntihar davranışı ciddi bir sağlık problemidir. İkiz, evlat edinme ve aile içi çatışmalar hakkında yapılan çalışmalarda genetik ve intihar arasında ilişki olduğu gösterilmiştir. CB1 reseptörleri kannabinoid-1 reseptör geni (CNR1) trafından kodlanmaktadır. CNR1 gen polimorfizminin (1359 G/A) majör depresyonu da içeren bir çok nöropsikiyatrik bozuklukla ilişkili olduğu gösterilmiştir. Bu çalışmada intihar girişimi ile CNR1 gen polimorfizmi arasında ilişki olup olmadığını belirlemek amaçlanmıştır. Yöntem: Çalışmaya katılan her hastadan periferal kan örnekleri alınıp kannabinoid geni (1359 G/A) içeren tek gen polimorfizmi çalışıldı. Bulgular: Bu çalışma intihar girişiminde bulunan 115 hasta (ortalama yaş: 25,57±8,52; 41 erkek) ve 69 sağlıklı kontrol grubuyla (ortalama yaş: 27,49±10,55; 38 erkek) yapıldı. Hasta grubuyla kontrol grubu arasında genotip dağılımı incelemesinde AG genotipi açısından iki grup arasında anlamlı bir fark bulundu (%21,7e karşı %44,9, p=0,001). AG genotiplilerin intihar girişimi nedeniyle acil servise başvurusu 3,3 kat daha düşük orandaydı (%95 CI: 1,6-6,8). CNR1 geni polimorfizmi A ve G allel sıklığı intihar girişiminde bulunan hastalarda sırasıyla %16,1 (n=37) ve %83,9 (n=193), kontrol grubu hastalarında ise %25 (n=31) ve %77,5 (n=107) olarak bulundu (p=0,127). AA genotipinin tamamı suisid girişiminde bulunan hasta grubundandı (n=6). AG genotip sıklığı daha önce psikiyatrik tanı almamış olan hastalarda, almış olan hastalara göre anlamlı olarak düşük bulunmuştur (sırasıyla %32 (n=38), %68 (n=17); p= 0,004). Sonuç: CNR1 rs1049353 (1359 G/A) gen polimorfizmi ile intihar girişimi arasında bir ilişki vardır. Sonraki araştırmalarla da desteklendiği taktirde CNR1 reseptör polmorfizmi intihar girişimini önleme ve belirlemede biyolojik bir test olarak kullanılabilir.
