CETP polymorphisms confer genetic contribution to centenarians of Hainan, south of China.

Objective: In this paper, we will discuss if the CETP polymorphism contributes to the centenarians in Hainan island.

Methods: We tested the TaqIB and I405V polymorphisms of CETP gene among 276 centenarians and 301 matched healthy individuals by AS-PCR and analyzed the data with SPSS software package (Version 19.0).

[Molecular characterization of 71 cases of glucose-6-phosphate dehydrogenase deficiency in Hainan province].

Objective: To molecularly analyze in Han and Li individuals of glucose-6-phosphate dehydrogenase deficiency in Hainan, China.

Methods: The amplification refractory mutation system (ARMS) was employed to detect G1376T, G1388A and A95G mutations. The coding regions and flanking intronic regions from the second to the thirteenth exons of G6PD gene was analyzed by DNA sequencing to characterize the gene mutations in samples without G1376T, G1388A and A95G mutations.

[Nine polymorphisms of fibrinogen gene and their association with plasma fibrinogen levels in Hainan Han population].

Objective: To investigate the allelic frequencies of polymorphisms of alpha Taq I and beta Bcl I, Hinf I A/C, 448 G/A, beta BsmA I G/C, +1689T/G, -148C/T, -249C/T, -455G/A in Hainan Han population and their association with plasma fibrinogen level.

Methods: Turbidmetric assay was used to measure plasma fibrinogen level of two hundred and thirty-eight healthy individuals. The genotypes were characterized by PCR-RFLP and sequence analysis.
