BACKGROUND: The single-nucleotide polymorphisms (SNPs) of apurinic/apyrimidinicendonuclease 1 (APE1), which has been implicated in cancers and the DNA base excision repair (BER) process, have not been thoroughly investigated in association with the risks of oxidative stress-related vitiligo.
OBJECTIVES: The aim of this study is to investigate associations between APE1 single-nucleotide polymorphisms 141T >G and 1349T >G and risk and prognosis of vitiligo.
MATERIAL AND METHODS: From June 2013 to June 2015, a total of 460 vitiligo patients were randomly recruited as a case group; 200 of these patients received narrow bound ultraviolet B (NB-UVB) treatment. Meanwhile, 460 healthy controls were included as a control group. Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) was performed to explore the distribution frequencies of genotypes.
RESULTS: Significant differences were detected between the case group and the control group in the frequencies of the 141T >G and 1349T >G genotypes. At 141T >G, compared with patients carrying the TG + GG genotype, male patients carrying the TT genotype aged more than 20 years with active non-segmental vitiligo, without a family history of vitiligo or other autoimmune diseases, exhibited an increased risk of vitiligo. Binary logistic regression analysis demonstrated that the TT genotype at 141T >G and the non-TT genotype at 1349T >G were independent risk factors for vitiligo development. At 1349T >G, compared with patients carrying the TT genotype, male patients carrying the TG + GG genotype aged more than 20 years with active non-segmental vitiligo, without a family history of vitiligo or other autoimmune diseases, exhibited an increased risk of vitiligo. Moreover, patients carrying 141TG + GG or 1349 TT genotypes had better photochromic effects, lower cumulative radiation doses, shorter treatment times, and earlier first photochromic times.
