This meta-analysis showed evidence that ELAC2 Ser217Leu and Ala541Thr polymorphisms were associated withprostate cancer risk, and might be low-penetrance susceptibility markers of prostate cancer.
Two HPC2 gene missense variants, Ser217Leu (Leu217) and Ala541Thr (Thr541) have been associated with incident prostate cancer cases in some studies, but not in others.
To determine the contribution of two HPC2/ELAC2 missense variants (Ser217Leu and Ala541Thr) to the risk of developing prostate cancer, we conducted a population-based case-control study of middle-aged men (40-64 years).
The ELAC2 gene has been proposed to be a prostate cancer susceptibility gene and is being referred to as HPC2, in part because three case-control studies suggested that two common polymorphisms (Ser217Leu and Ala541Thr) are associated with risk.
The recently identified prostate cancer susceptibility gene ELAC2 ( HPC2) harbors two common missense variants, a serine to leucine substitution at residue 217 (Leu217) and an alanine to threonine substitution at residue 541 (Thr541).
To test the hypothesis that variation in the putative prostate cancer susceptibility gene ELAC2 contributes to the elevated risk of prostate cancer in Afro-Caribbean males from Tobago, we genotyped the S217L and A514T polymorphisms, previously reported to be associated with prostate cancer risk in a large sample of cases and controls.
