However, recent data from 23,868 men with PCa and 23,051 controls from 25 studies within the international PRACTICAL Consortium indicate that three intronic single nucleotide polymorphisms (SNPs) in the ALDH1A2 gene were associated with longer survival of PCa patients, implying its enhanced activity and quick utilization of ACH [32]. The gene discussed is ALDH1A2; the disease is posterior cortical atrophy.
