Gene Expression + Phenotype

Nullizygous females show altered Na+ and water reabsorption in the kidney proximal tubules. Males hemizygous for a null allele show increased transcellular Na+ reabsorption in the thick ascending limb, higher renal oxygen consumption, medullary hypoxia, and susceptibility to ischemic renal injury.
