Sentence |

RNASEL and RNASEL-inhibitor variation and prostate cancer risk in Afro-Caribbeans. |
| T2 |
83-94 |
Sentence |
denotes |
BACKGROUND: |
| T3 |
95-170 |
Sentence |
denotes |
Afro-Caribbeans from Tobago are at high risk of developing prostate cancer. |
| T4 |
171-311 |
Sentence |
denotes |
This elevated risk of prostate cancer is shared by populations of African ancestry living in diverse environments in the Western hemisphere. |
| T5 |
312-444 |
Sentence |
denotes |
Variation in the ribonuclease L (RNASEL) gene has recently been reported to be associated with an increased risk of prostate cancer. |
| T6 |
445-592 |
Sentence |
denotes |
However, whether RNASEL variation contributes to the increased risk of prostate cancer observed in populations of African ancestry remains unclear. |
| T7 |
593-601 |
Sentence |
denotes |
METHODS: |
| T8 |
602-796 |
Sentence |
denotes |
We resequenced the positional candidate gene RNASEL in 48 prostate cancer cases and genotyped the previously reported R462Q and D541E polymorphisms in 230 prostate cancer cases and 458 controls. |
| T9 |
797-897 |
Sentence |
denotes |
We also examined the inhibitor of RNASEL (ABCE1) for variation associated with prostate cancer risk. |
| T10 |
898-906 |
Sentence |
denotes |
RESULTS: |
| T11 |
907-1035 |
Sentence |
denotes |
We found no evidence of association between R462Q and D541E polymorphisms and prostate cancer risk in our case/control analysis. |
| T12 |
1036-1132 |
Sentence |
denotes |
A novel variant (K294E) was identified in a single heterozygous individual with prostate cancer. |
| T13 |
1133-1290 |
Sentence |
denotes |
We also observed a 20 bp insertion/deletion polymorphism 1,109 bp upstream of the initiation codon, but this variant was not associated with prostate cancer. |
| T14 |
1291-1408 |
Sentence |
denotes |
We identified 16 single nucleotide polymorphisms in the ABCE1 gene, only 3 of which had a minor allele frequency >5%. |
| T15 |
1409-1552 |
Sentence |
denotes |
A common A/G transition -1,071 bp from the transcriptional start site was genotyped and showed no evidence of association with prostate cancer. |
| T16 |
1553-1565 |
Sentence |
denotes |
CONCLUSIONS: |
| T17 |
1566-1778 |
Sentence |
denotes |
Our results suggest that common variation in the putative prostate cancer susceptibility gene, RNASEL, or its inhibitor does not contribute significantly to prostate cancer risk in this Afro-Caribbean population. |
