ATM and pure red-cell aplasia: Another study including 5560 PrCa patients and 3353 controls of European ancestry showed that the likelihood of carrying ATM PVs was greater in PrCa cases than in controls (1.2% vs. 0.24%, OR = 4.4, 95%CI, 2.0–9.5; p < 0.0001) and cases diagnosed before the age of 65 years than those diagnosed after 65 years of age (OR = 4.9, 95%CI, 2.2–11.1; p < 0.0001) [97].
