چکیده

مقدمه: کم خونی، شرایطی است که در آن غلظت هموگلوبین (Hemoglobin) Hb و یا تعداد گلبول‌های قرمز خون RBC (Red blood cell) کمتر از حد طبیعی است و برای تأمین نیازهای فیزیولوژیکی فرد کافی نیست. چندین پلی‌مورفیسم ژنتیکی مرتبط با وضعیت آهن شناسایی شده است. هدف از این مطالعه، بررسی ارتباط پلی‌مورفیسم rs4820268G>A با آنمی فقر آهن در شهر سنندج بود.
روش‌ها: در این مطالعه‌ی‌ مورد- شاهدی مربوط به بهار سال 1394، تعداد 120 نفر شامل 40 فرد مبتلا به آنمی فقر آهن و 80 فرد سالم (بر اساس نتایج تست فریتین؛ هموگلوبین، (Complete blood count) CBC و (Mean corpuscular volume) MCV) با تکنیک RFLP-PCR و آنزیم HPY99I بررسی شدند.
یافته‌ها: فراوانی ژنوتیپ‌های AA AG و GG در بیماران (10) 25، (4) 10 و (26) 65 درصد و در گروه سالم (57) 25/71، (17) 25/21 و (6) 5/7 درصد بود. نسبت شانس (Odds ratio) OR ژنوتیپ GG، 22 برابر نسبت به AA خطر بیماری را بیشتر می‌کند. همچنین، آزمون هاردی- وینبرگ (Hardy-Weinberg) نشان داد که جمعیت مورد ارزیابی در این تجزیه و تحلیل متعادل است.
نتیجه‌گیری: نتایج مطالعه نشان داد، رابطه‌ی معنی‌داری بین ژنوتیپ GG و AA به ترتیب با بیماری و سلامتی وجود دارد (001/0 > P). به عبارتی، افراد دارای ژنوتیپ GG دارای HGB، MCV و Ferritin پایین‌تری نسبت به افراد دارای ژنوتیپ AA و AG بودند.

چکیده [English]

Background: Anemia is a condition in which the concentration of hemoglobin (Hb) or red blood cell count (RBC) is lower than normal and is not sufficient to meet the physiological needs of the individual. Several genetic polymorphisms associated with iron status have been identified. The aim of this study was to investigate the relationship between rs4820268G > A polymorphism and iron deficiency anemia in Sanandaj. 
Methods: In this case-control study, 120 individuals including 40 patients with iron deficiency anemia (based on the results of ferritin test; hemoglobin, CBC and MCV) alongside 80 healthy individuals were studied. After DNA extraction, genotypes of individuals were examined by RFLP-PCR technique and the effect of HPY99I enzyme.
Findings: The frequency of AA, AG and GG genotypes among patients were (25) 25, (4) 10 and (26) 65% and in healthy group (57) 71.25, (17) 21.25 and (6) 5/ 7%, respectively. The odds ratio (OR) of the genotype, GG, is 22 times higher than that of AA. Also, the Hardy-Weinberg test showed a balanced population in this analysis.
Conclusion: The results showed a significant relationship between GG and AA genotypes with disease and health, respectively (P < 0.001). In other words, individual with GG genotype had lower Hb, MCV and Ferritin than people with AA and AG genotypes.
