AIRE and Hypocalcemia: Next, to test the interactions between FHL1 and hypocalcemia-related proteins, we have manually assembled a list of 11 genes (PTH, CALC1, PTHRP, TBX1, GCM2, CASR, AIRE, GNA11, GATA3, GNAS, and TRPM6), which code for proteins known to be involved in calcium sensing/metabolism with direct connection to primary hypoparathyroidism.
