ERCC2 and posterior cortical atrophy: Lavender et al. [24] found that individuals possessing at least one XPD 312 Asn allele had a 1.3- to 8.6-fold higher PCa risk when compared to those with the 312 Asp/Asp genotype, however, there were no significant differences in the allele frequencies between cases and controls for Gln751Lys polymorphism.
