ITPR3

ITPR3 -- why is it a big deal?

1) It affects calcium function in cells, which is vital for many cell functions.


2) It has been linked to many different diseases, including cancer (lung, bone, breast to name a few)


3) Mutations cause CMT1J, which sometimes causes severe disability or even death.
