… dataset to replicate these findings in a within-sibship analysis. Population attributable risk calculations demonstrated that autozygosity resulting from consanguinity accounts for 8-15% of type 2 diabetes cases among British Pakistanis. Simulation studies indicated these associations likely stem …
