A cannulated offset drill guide and surgical methods for repairing Bankart lesions. The gate has an intrinsic capacitance which, when the gate is activated, is added to the capacitance of the floating diffusion region, providing a low conversion gain readout. A radio performance estimator generates for each selective combination of RF signals at least one non-RF radio performance indicator representative of the quality of the RF signals in the combination. In this way, portions of data collection and reporting may be shared within the program initiative and its various, associated assessment projects. Data from a population-based study of 14,783 individuals support rs2231142 as the causal variant in the region and show highly significant associations with urate levels and gout.
