Profesyonel Voleybolcularda Katekol-O-Metiltransferaz (COMT) rs4680 Polimorfizminin Belirlenmesi

Yıl 2019, Cilt: 4 Sayı: 1, 1 - 6, 20.06.2019

Öz

Katekol-O-Metil Transferaz (COMT) katekolamin nörotransmitterlerin (dopamin, epinefrin,
norepinefrin) inaktivasyonunda rol alır. COMT genindeki keşfedilen fonksiyonel polimorfizmlerin COMT
enzim aktivitesinde değişime sebep olduğu bilinmektedir. Çalışmamızda, COMT geninin Val(108/158)
Met rs4680 polimorfizmi profesyonel voleybolcularda incelenmiş ve COMT rs4680 polimorfizminin
voleybolcularda genotip ve allel dağılımlarının belirlenmesi amaçlanmıştır. Bu kapsamda 21 profesyonel
voleybol sporcumuz çalışmamıza katılmıştır. Genotipleme çalışması Swab DNA izolasyonu sonrasında
gerçek zamanlı polimeraz zincir reaksiyonu (RT-PCR) ile tamamlanmıştır. Araştırmamızın sonuçlarına
göre sporcularımızda AA, AG ve GG genotip dağılımları; 6 sporcumuzda (%29) GG, 7 sporcumuzda (%33)
GA ve 8 sporcumuzsa ise (%38) AA genotipi saptanmıştır. Allellik dağılımlarında ise G Alleli 19 (%45) ve
A Alleli 23(%55) olarak bulunmuştur. Kohortumuzda AA genotipi diğer genotiplere göre, A alleli G alleline
göre daha yüksek bulunmuştur. Bulgularımıza göre voleybol sporcularının düşük aktiviteli AA genotipinin
fazla bulunması voleybol sporuna yatkınlık için biyolojik belirteç olabileceğini kanıtlanmıştır. Çalışmamız
COMT rs4680 polimorfizminin voleybolcularda etkisini inceleyen ilk araştırma niteliğindedir.

Determination of Catechol-O-Methyltransferase (Comt) rs4680 Polymorphism in Professional Volleyball Players

Catechol-O-Methyl Transferase (COMT) is involved in the inactivation of catecholamine neurotransmitters

(dopamine, epinephrine, norepinephrine). The discovered functional polymorphisms in the COMT

gene are known to cause changes in COMT enzyme activity. In our study, the Val (108/158) Met rs4680

polymorphism of the COMT gene was examined in professional volleyball players and it was aimed to

determine the genotype and allele distributions of COMT rs4680 polymorphism in volleyball players.

In this context, 21 professional volleyball athletes participated in our study. The genotyping study was

completed with real-time polymerase chain reaction (RT-PCR) after swab DNA isolation. According to

the results of our study, AA, AG and GG genotype distributions in our athletes; In 6 of our athletes (29%),

7 of our athletes (33%) had GA and 8 of our athletes (38%) had AA genotype. When we look at the allel

numbers of our volleyball players, G Allele was 19 (45%) and A Allele 23 (55%). AA genotype in our

cohort was higher than other genotypes, compared to A allele G allele. According to our findings, volleyball

athletes’ low activity AA genotype has been proved to be a biomarker for predisposition to volleyball sport.

Our study is the first research to examine the effect of COMT rs4680 polymorphism on volleyball players.
