The polygenic nature of inhibitors in hemophilia A: results from the Hemophilia Inhibitor Genetics Study (HIGS) Combined Cohort.
(2013) In Blood 121(8). p.1446-1454- Abstract
- Studies of determinants of development of inhibitory antibodies to factor VIII in people with hemophilia A indicate a complex process involving multiple factors. The Hemophilia Inhibitor Genetics Study Combined Cohort was formed to extend understanding of the genetic background of risk. The study group contains 833 subjects from three independent cohorts: brother pairs and singletons with and without a history of inhibitors, as well as 104 brother pairs discordant for inhibitor status. Using an Illumina iSelect platform, 13,331 SNPs from 1,081 genes, primarily immune response and immune modifier genes, were typed. Each cohort was analyzed separately with results combined using a meta-analytic technique. After adjustment for potential... (More)

Each cohort was analyzed separately with results combined using a meta-analytic technique. After adjustment for potential confounders, 53 SNPs were significant predictors of inhibitor status using the criteria of odds ratios (OR) in the same direction in all cohorts, or allowing for a 20% interval around an OR of 1 in one of the three, and significant in at least two. Of the 53, 13 markers had meta p-values of <0.001. Eight of the 53 were significant predictors among the discordant pairs. Results support the complexity of the immune response, and encourage further research with the goal of understanding the pathways involved. (Less)
