Objective:
To study the relationship between polymorphism of genes XPA, XPC, XPD, XRCC1 and susceptibility to acute lymphoblastic leukemia (ALL) in a Chinese population.
Methods:
Polymorphism were determined by a case-control study through matrix-assisted laser desorption/ionization tandem time-of-flight mass spectrometry method of Mass-ASSAY platform in 114 confirmed ALL cases and 169 age- and sex-matched controls, so as to compare the relationship between different genotypes and ALL risk.
Results:
Multivariate logistic regression analysis revealed that individuals carrying at least one 23G variant allele (AG/GG genotypes) had a significantly increased risk for ALL (adjusted OR 2.02; 95%CI 1.08 - 3.78) compared with the wild-type genotype (23AA), and evidence that positive interactions between the polymorphisms in XPC C499T and XPA A23G might occur. Furthermore, individuals with both putative risk genotypes had a significantly higher risk (adjusted OR 5.60; 95%CI 1.57 - 19.90), compared with those with both wild-genotypes. By contrast, no significant association was observed between the XPD T751G, XRCC1 G399A, C194T polymorphism and ALL risk.
Conclusions:
XPA A23G and XPC C499T polymorphism may contribute to the risk of developing ALL. There are significant combinations between XPC C499T and XPA A23G.

Lethal Alleles
Lucien Cuénot discovered lethal alleles in 1905 while studying the inheritance of coat color in mice. The agouti gene is responsible for the color of the coat in mice. This gene codes for an agouti-signaling protein, which is responsible for melanin distribution in mammals. The wild-type allele gives rise to gray-brown coat color in mice, while the mutant allele gives rise to yellow coat color. In addition to coat color, the agouti gene is associated with the yellow...
