Abstract:
| Fanconi anemia (FA) family of proteins participates in the DNA repair pathway by homologous recombination, and it is currently formed by 13 genes. Some of these proteins also confer susceptibility to hereditary breast and ovarian cancer (HBOC), since FANCD1 is the BRCA2 breast cancer susceptibility gene, and FANCN/PALB2 and FANCJ/BRIP1 explain 2% of non-BRCA1/2 HBOC families. Thus, there is an important connection between FA and BRCA pathways. In a previous case-control association study analysing FANCA, FANCD2 and FANCL, we reported an association between FANCD2 and sporadic breast cancer (BC) risk (OR = 1.35). In order to know whether variants in other FA genes could also be involved in this association, we have extended our study with the rest of FA genes and some others implicated in the BRCA pathway. We have also analyzed the correlation with survival, nodal metastasis and hormonal receptors (ER- and PR-). A total of 61 SNPs in ten FA genes (FANC-B, -C, -D1, -E, -F, -G, -I, -J, -M, -N) and five FA related genes (ATM, ATR, BRCA1, H2AX and USP1) were studied in a total of 547 consecutive and nonrelated sporadic BC cases and 552 unaffected controls from the Spanish population. Association analyses reported marginal statistically significant results with the minor allele of intronic SNPs in three genes: BRCA1, BRCA2/FANCD1, and ATM. Survival association with SNPs on FANCC and BRCA2/FANCD1 genes were also reported. Sub-group analyses revealed associations between SNPs on FANCI and ATM and nodal metastasis status and between FANCJ/BRIP1 and FANCN/PALB2 and PR- status. |
