CLEC12A and rheumatoid arthritis: The gene cluster in which MICL is located has been linked with RA,3, 5 and we recently reported that polymorphisms of hMICL could potentially be associated with this disease.12 We reassessed the contribution of this gene within the much larger cohort of the Wellcome Trust Case Control Consortium.21 However, there was no genome-wide significant association of any polymorphism in and around Clec12A with RA (figure 5).
