TMPRSS6 gene mutations can result in iron deficiency anemia (IDA) and cause an increased iron-regulatory hormone, hepcidin, levels. TMPRSS6 encodes a serine protease, matriptase-2, which functions as negative regulatory protein of hepcidin transcription. Thus, TMPRSS6 variations might be risk factors for IDA. The aim of the study was to investigate the association of rs855791, rs4820268, rs5756506, rs2235324, rs2413450, rs2111833, rs228919, and rs733655 SNPs in TMPRSS6 gene with IDA susceptibility and iron-related clinical parameters. The study consisted of 150 IDA patients and 100 healthy controls. We analyzed the genotype distributions by using Real-Time polymerase chain reaction (Real-Time PCR) technique. We did not find any statistically differences for all SNPs between patients and controls (P > 0.05). In IDA patients, variations rs855791 and rs2413450 were associated with increased RBC (P = 0.03) and TIBC (P = 0.04), respectively. Also, increased of TIBC for rs4820268 (P < 0.05). On the other hand, in control group, rs5756506 was associated with two parameters, Hb (P = 0.02) and Hct (P = 0.03). We did not find markedly hepcidin levels in IDA patients compared to controls (P = 0.32). Our findings suggest that TMPRSS6 variations may not be risk factors for IDA. However, TMPRSS6 polymorphisms are associated with increased many iron-related hematological parameters.
