Summary: | To analyze the correlation between polymorphisms of the vitamin D receptor gene (Taq I and Fok I) and the aggressive periodontitis by FBAT method.
93 AgP nuclear families including 93 probands and their 155 relatives were recruited. The genotype frequency and polymorphism for VDR for the patients and their pedigree were detected by using polymerase chain reaction (PCR) combined with restriction fragment length polymorphism (RFLP).
The frequency of allele T and t accounted for 94.6 % and 5.4 % in the total populations. No tt genotype were detected. The fathers of probands carried more allele t than the mothers(9.8% vs 1.6%, P=0.005). The frequency of allele F and f accounted for 57.1 % and 42.9 % in the total populations. The result of family based associated test (FBAT) including additive model, dominant model and recessive model showed that different alleles of Taq I and Fok I had no correlation with the onset of AgP(P>0.05).
This was the first time to detect the VDR gene polymorphisms in Chinese families. T |
