phenotype observed in females
phenotype observed in males
N normal phenotype
• mice, especially females, are born at less than Mendelian frequency

• trend towards lower body weight

• impaired balance control at 12 weeks of age
• take three times longer than controls to turn around on a thin rod suspended above the ground, and many fell off while attempting to do so
• fall off a rotating rod earlier than control mice at 12 weeks of age
• unable to hang as long from an inverted screen or a horizontal bar at 12 weeks of age
• more spontaneous activities than controls at 12 weeks of age
• stay significantly longer than controls in free-running wheels at 12 weeks of age
• run longer distance over a 23-hour period on a free-running wheel

nervous system
• more hyperpolarized resting membrane potential of cerebellar Purkinje cells in acute brain slices than in controls
• restored by tolbutamide, a specific inhibitor of KATP channels
• substantially lower action potential frequency of cerebellar Purkinje cells in acute brain slices in both cell-attached and whole-cell recordings
• restored by tolbutamide
• the ATP sensitivity of the native muscle ATP-sensitive potassium (KATP) channel is reduced compared with that of control mice in patch-clamp recordings of isolated muscle fibers

• unable to lift weights as effectively or to hang as long from an inverted screen or a horizontal bar at 12 weeks of age
