Abstract

Objective: In this study, we investigated whether methionine synthase (MTR) A2756G and methionine synthase reductase (MTRR) A66G gene polymorphisms were related with infertility. Materials and methods: Blood samples of 117 infertile (66 azoospermia, 51 oligozoospermia) cases and 70 healthy men were collected and genotyped for MTR A2756G and MTRR A66G polymorphisms. Results: In control and study groups MTR A2756G genotypes were 64% AA, 34% AG, 1% GG and 54% AA, 39% AG, 7% GG , respectively, and the frequency of the G allele in the study group was increased compared to control group (p<0.05). MTRR A66G genotypes were 9% AA, 79% AG, 13% GG in control group and 4% AA, 73% AG, 23% GG in control group without statistically significant difference (p>0.05). Conclusion: MTR A2756G gene polymorphism may have an important effect on the evolution of male infertility. Finding of increased G allele frequency of study group will lead to further and larger sample-size studies.

Özet

Amaç: Bu çalışmada metiyonin sentaz (MTR) ve metiyonin sentaz redüktaz (MTRR) A2756G ve A66G gen polimorfizmlerinin infertilite ile ilişkisinin olup olmadığı araştırılmıştır. Gereç ve yöntem: Bu amaçla 66 azospermi ve 51 oligozoospermi olmak üzere toplam 117 infertilite olgusu ile 70 sağlıklı bireyin kan örnekleri toplanarak MTR A2756G ve MTRR A66G genotiplendirmeleri yapılmıştır. Bulgular: Kontrol ve çalışma grubunda MTR A2756G genotipleri sırasıyla %64 AA, %34 AG, %1 GG ve %54 AA, %39 AG, %7 GG olup, G allelinin artışı kontrol grubuna oranla çalışma grubunda istatistiksel olarak anlamlı bulunmuştur (p 0.05). Sonuç: Erkek infertilitesi gelişiminde MTR A2756G polimorfizminde G allelin sadece hasta grubunda yüksek bulunması daha ileri ve yüksek hasta sayılı çalışmalara ışık tutacaktır.
