PG - 2451-4 AB - OBJECTIVE: To explore the association of vitamin D receptor ApaI and TaqI gene polymorphisms with pigmented pretibial patches (PPPs) in type 2 diabetes mellitus (T2DM) patients. METHODS: A total of 233 patients with T2DM were enrolled. Patients were assigned to PPPs group (n=106) or non-PPPs (n=127) according to the presence of PPPs. Allelic and genotypic comparisons of VDR-TaqI and VDR-ApaI between the different groups were evaluated by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). RESULTS: The genotype and allele gene frequency were similar at ApaI in two groups (P>0.05). The PPPs group showed a higher frequency of TT allele at TaqI in the T2DM (95%) when compared to that of non-PPPs group (87%), while the frequency of Tt and tt allele were lower in PPPs group than non-PPPs group in T2DM (5% vs 13%, all P<0.05). The frequency of T allele were higher at TaqI in PPPs group (98%) than non-PPPs group (93%) in T2DM, while PPPs had a lower frequency of t allele (2% vs 7%, all P<0.05). CONCLUSION: It seems that gene polymorphisms of VDR-TaqI, not VDR-ApaI, contributes to the risk of PPPs in T2DM patients in the Han nationality in Tianjin area.
