Abstract Abstract 870 Introduction: Despite recent advances in technology and supportive care, hematopoietic cell transplant (HCT) continues to be associated with high morbidity and mortality. Since the therapies used in HCT induce DNA damage that is repaired by the base excision repair (BER) pathway we hypothesized that single nucleotide polymorphisms (SNPs) in BER genes may influence HCT outcomes. Methods: We evaluated the association between tagSNPs and functionally important SNPs (n= 179) in the BER pathway with transplant related mortality at one year (TRM) and disease relapse in a cohort of 470 recipients of allogeneic HCT for hematologic malignancies at the University of Minnesota between 1998 and 2007 from a HLA-identical sibling donor, HLA-matched or mismatched unrelated donor (URD) or single umbilical cord graft. Results: After adjustment for age at transplant, donor type, race, and conditioning regimen, four SNPs in OGGI, LIG3 and MUTYH1 genes (rs159153, rs3135974, rs3219463, rs3219476) were associated with increased risk of TRM whereas two SNPs in TDG gene (rs167715, rs2374327) were associated with decreased risk of TRM at one year (p≤0.01). Patients with increasing numbers of deleterious alleles in the BER pathway showed an increased cumulative incidence of TRM at one year (14% for ≤ 1 deleterious allele vs. 51% for ≥ 4 deleterious alleles; p<0.001). One SNP, rs3135974, in LIG3 gene was associated with decreased risk of disease relapse (p<0.001) post HCT. Conclusions: Single nucleotide polymorphisms in the BER pathway are significantly associated with both TRM and disease relapse, thus supporting the hypothesis that genetic polymorphisms in the BER pathway are involved in the pathophysiology of TRM and disease relapse. If confirmed in independent cohorts, these SNPs may indicate patients who might benefit from altered or less DNA damaging conditioning regimens. Disclosures: No relevant conflicts of interest to declare.

Abstract Endometriosis is a major health issue among women of reproductive age. However, its etiology has not yet been completely understood. We investigated 10 single nucleotide polymorphisms from six novel nucleotide excision repair genes and the susceptibility to endometriosis. A total of 153 patients with endometriosis were recruited during 2000–2010 from central Taiwan. Pathological confirmation was necessary for all patients, and exclusion criteria included the presence of leiomyoma, adenomyosis, or cancer of the uterine, cervix, or ovary and a prescription of hormone therapy. Furthermore, a total of 636 age-matched individuals without endometriosis were recruited during the same time period from central Taiwan. The polymerase chain reaction coupled with restriction fragment length polymorphism methodology was applied for genotyping. The multivariate logistic regression analysis showed that subjects carrying the ERCC1 rs11615 TT (OR = 2.04, 95% CI = 1.36–3.41), ERCC2 rs1799793 AA (OR = 1.86, 95% CI = 1.14–3.11), and ERCC6 rs2228528 AA genotypes (OR = 1.79, 95% CI = 1.13–2.83) exhibited significantly increased risks of developing endometriosis compared with their counterparts carrying the wild-type genotypes. This study suggests that certain single nucleotide polymorphisms of nucleotide excision repair genes excision repair cross-complementation group 1 (ERCC1, ERCC2, and ERCC6) predispose women to the development of endometriosis.
