This year has been fairly good for our lab; a few years ago we found an association of rs17849502 with SLE. Finally, after significant work by our collaborators, we managed to demonstrate a functional significance of this SNP with possible importance for SLE. Changing H389 to Q reduces the function of the NADPH oxidase complex by 50% in Vav dependent Fcγ response.
