Several variants were significantly or marginally significantly associated with sporadic, not hereditary PCa risk, including R293X in white men (random effect OR = 1.34, P = 0.09) and D174Y in black men (random effect OR = 2.41, P = 0.04).
Meta-analyses revealed significant associations of prostate cancer with MSR1 IVS7delTTA, -14,742 A>G, and Arg293X in European Americans; Asp174Tyr in African Americans; RNASEL Arg462Gln in European American's overall and in family history-negative disease; and Glu265X in family history-positive European Americans.
In our sample, the rare Asp174Tyr missense change was identified nearly twice as frequently in men with prostate cancer (6.8%) compared with unaffected controls (3.6%; P = 0.14).
