Cantu syndrome (CS) is a condition characterized by a range of anatomical defects,
including cardiomegaly, hyperflexibility of the joints, hypertrichosis, and craniofacial
dysmorphology. CS is associated with multiple missense mutations in the genes encoding
the regulatory sulfonylurea receptor 2 (SUR2) subunits of the ATP-sensitive K+(K ATP)
channel as well as two mutations (V65M and C176S) in the Kir6. 1 (KCNJ8) subunit.
