As expected the study found significant linkage to the suspected HLA region, but more importantly found additional, previously unknown and significant linkages at 19p13.1 (with a peak at marker D19S899), and at 6q21-22, which is ~70 cm downstream from the HLA region in question. The researchers conclude: "Significant linkage of celiac disease to chromosome region 19p13.1 was detected in our genome-wide screen. These results were confirmed by the association of D19S899 to celiac disease in an independent case-control cohort. Furthermore, we identified a possible second celiac disease locus on chromosome region 6q21-22."
The study was dedicated to the memory of Lodewijk Sandkuijl (1953-2002), who died shortly after its completion. He was an inspiration to the researchers and was a world expert on biostatistics.
