A genome wide association study was performed using 500.568 single nucleotide polymorphisms (SNPs) in two series of homogeneously treated MM patients: one with ONJ (22 MM cases) and another without ONJ (65 matched MM controls). Four SNPs (rs1934951, rs1934980, rs1341162 and rs17110453) mapped within the Cytochrome P450-2C gene (CYP2C8) showed a different distribution between cases and controls with statistically significant differences (p=1.07x10(-6),p=4.231x10(-6), p=6.22x10(-6) and p=2.15x10(-5), respectively). SNP rs1934951 was significantly associated with a higher risk of ONJ development even after Bonferroni correction (P corrected value=0.02). Genotyping results displayed an overrepresentation of the T allele in cases as compared with controls (48% vs. 12%). Thus, individuals homozygous for the T allele had an increased likelihood of developing ONJ (Odds ratio 12.75, 95% confidence interval 3.7 to 43.5). | | Language | ENG | | Pub Type(s) | JOURNAL ARTICLE
