Aanstoot et al. [22], using immunoprecipitation assays with radiolabelled cell extracts and assessing the presence of antibodies by detecting bands on autoradiographs, antibodies to Glima 38 (i.e. Tspan7) were found in only 19% of 86 recently diagnosed patients with type 1 diabetes aged 0.8–57 years. The gene discussed is TSPAN7; the disease is type 1 diabetes mellitus.
