This meta-analysis showed evidence that ELAC2 Ser217Leu and Ala541Thr polymorphisms were associated with prostate cancer risk, and might be low-penetrance susceptibility markers of prostate cancer.
Two non-synonymous single-nucleotide polymorphisms (SNPs), Ser217Leu and Ala541Thr, in the elaC homolog 2 (Escherichia coli) (ELAC2) gene have been related to prostate cancer risk in previous studies, though with inconsistent results.
We produced recombinant human tRNase ZL's, which contain one to three amino-acid substitutions from three missense mutations (Ser217Leu, Ala541Thr, and Arg781His) that are associated with the occurrence 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.
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).
The prevalence of the HPC2 Ala541Thr allele was similar in men with prostate cancer (6.3%), men with other prostatic conditions (6.8%), and healthy women (6.3%) (P = .83).
