Abstract:
Present research was undertaken with the aim to assess the association of VDR gene FokI polymorphism with
T2DM in local population. The study comprised of 100 T2DM patients (DG) and 50 normal individuals (CG) groups.
Demographic parameters; age, gender, BMI and blood pressure were recorded. Fasting glucose (FG), HbA1c, vitamin D,
liver function parameters, renal function parameters and lipid profile were measured. Significantly higher (P<0.05) BMI
(34.6±11.3 vs. 24.9±4.0kg/m2
), sBP (141±16 vs. 124±14mm Hg), dBP (81±8 vs. 76±7mm Hg), FG (145±5.54 mg/dL vs.
80±3.55mg/dL, HbA1c (7.43±0.69 % vs. 4.85±0.33%) were evident in DG as compared to CG. Prominent reduction
(P<0.05) in vitamin D levels (13.69±1.85mg/dL) manifested in case subjects than that of control subjects
(22.36±2.34mg/dL) as a negative correlation existed between HbA1c and vitamin D. Compared to control participants,
substantially different FokI allele distribution was observed in T2DM patients. Current study s also showed no
significant link between FokI genotype and the biochemical parameters. Present study endorsed the fact that diabetic
patients have hypovitaminosis D and variable VDR polymorphisms. However, confirmational studies are indecisive and
warrants further research.
