Recipient genotypes of rs12559701 are associated with the risk of cGVHD in the HLA-10/10-matched sibling cohort. (A) Cumulative incidence of cGVHD according to recipient rs125597901 genotypes and gender in the replication cohort. (B) Locus-zoom plot shows -log₁₀ (P values) for association with cGVHD in the combined discovery and replication cohorts as a function of position in a 0.5 Mb region on either side of rs12559701 on chromosome X. Correlation coefficient r² values for linkage disequilibrium with rs12559701 are coded according to the inset. Genes within this region are displayed in the lower panel.
