Association study of rs10768683 and rs968857 polymorphisms with transfusion-dependent thalassemia (TDT) in a southern Iranian population

Previous studies reported that detection of polymorphisms inherited through paternal model could be potential markers for the Non-Invasive Prenatal Diagnosis (NIPD) of β-thalassemia. The aim of the current study was to find out the associations of rs10768683 and rs968857 with transfusion-dependent thalassemia (TDT) in a southern Iranian population. A total of 175 subjects were investigated, divided into patients with TDT as case group (n = 75) and healthy people as control group (n = 100). Genomic DNAs were extracted from peripheral blood using salting out procedure. Genotyping rs10768683 and rs968857 was carried out by ARMS-PCR, then statistical analyses were assessed using SPSS, and Medcalc ver. 18 software. Data showed that rs10768683 was statistically significant in co-dominant model of inheritance (P = 0.025, OR = 2.11 [1.08-4.15]) and genotype frequencies of CG among controls and cases were 0.68 and 0.80, respectively. However, according to genotype frequencies, there was no association between rs968857 and TDT among cases and healthy controls in any models of inheritance. In conclusion, the present study showed the association of rs10768683 with major β-thalassemia through ARMS-PCR techniqu
