چکیده

مقدمه و هدف: سقط خود بخودی طبق تعریف سازمان بهداشت جهانی ختم حاملگی یا تولد نوزاد کمتر از 500 گرم قبل از هفته بیستم و دو حاملگی تعریف شده است. عوامل مختلفی می‌تواند موجب سقط مکرر گردد. از جمله علل ژنتیکی می‌توان به تاثیر برخی از پلی‌مورفیسم‌های ژنتیکی اشاره نمود. ژن فاکتور رشد اپیتالیوم عروقی (VEGF) از جمله ژن‌های کلیدی و مهم در رگ زایی است. متیلین تتراهیدروفولات دهیدروژناز سیکلوژناز و فورمیل تتراهیدرو فولات سنتتاز I (MTHFD1) در متابولیسم فولات نقش دارد. هدف از این تحقیق بررسی پلی مورفیسم ژنVEGF وMTHFD1 در ارتباط با سقط مکرر خود به خودی در زنان شهر تهران می‌باشد.
روش مطالعه: از 50 زن مبتلا به بیماری سقط مکرر و 10 زن سالم بدون سابقه سقط نمونه خون جمع آوری شد. DNA ژنومی از لوکوسیت‌های خون محیطی استخراج گردید. پلی‌مورفیسم ژنVEGF rs3025039 وMTHFD1 rs2236225 باPCR بررسی و به وسیله الکتروفورز ژل آگارز مورد تجزیه و تحلیل قرار گرفت. آنالیز آماری توسط نرم‌افزار FinchTV انجام شد.
نتایج: فراوانی ژنوتیپ‌های CC و CT برای جهش rs2236225 VEGFA به ترتیب در گروه بیمار 86% و 14% و در گروه کنترل پلی مورفیسم 90% و 10% بود. فراوانی ژنوتیپ‌های GGو GA برای جهش rs3025039 MTHFD1 به ترتیب در گروه بیمار 82% و 18% بود و و در گروه کنترل پلی مورفیسم دیده نشد.
نتیجه‌گیری: نتایج نشان داد که بین پلی‌مورفیسم VEGFA و MTHFD1 با سقط مکرر رابطه معنادار وجود دارد. مطالعه پلی‎مورفیسم ژن MTHFD1 در جمعیت‌ها می‌تواند به عنوان مارکر تشخیصی در استعداد ابتلا به سقط مکرر باشد.

چکیده [English]

Introduction and Aim: According to the WHO definition, recurrent miscarriage is a consecutive pregnancy loss before weeks 22. Different factors involved in recurrent abortion as a multifactorial disease. Genetic factors are one of the important factors associated with recurrent abortion. VEGFA (Vascular Endothelial Growth Factor A) is one of the important gene in angiogenesis. MTHFD1 (Methylenetetrahydrofolate Dehydrogenase, Cyclohydrolase, And Formyltetrahydrofolate Synthetase 1) is a protein-coding gene that metabolism folate. The goal of this article is to assess the association between single nucleotide polymorphisms of VEGFA and MTHFD1 and the recurrent miscarriage in Iranian women.
Material and method: The study group was 50 women with recurrent miscarriages and the control groups consisted of 10 women with at least two successful pregnancies and no miscarriages. The DNA extracted from leucocytes cells. PCR was used to find the association between VEGFA and MTHFD1 genes and recurrent miscarriages. Analyzing performed with FinchTV software after data sequencing.
Result: Our results showed that the polymorphism frequency of CC and CT in rs2236225 VEGFA were 86% and 14% in women with recurrent miscarriages and 90% and 10% in the control group. the polymorphism frequency of GG and GA in rs3025039MTHFD1 were 82% and 18% in women with recurrent miscarriages and no polymorphism was detected in the control group.
Conclusion: These results showed that there is an association between single nucleotide polymorphisms of VEGFA and MTHFD1 and the recurrent miscarriage in Iranian women. Furthermore, MTHFD1 polymorphism could be a molecular marker in the diagnosis of recurrent miscarriage.
