homeostasis/metabolism
• homozygotes exhibit high levels (10-20 mg/dl) of phenylalanine in the blood compared to control levels of 2-4 mg/dl
• serum levels of nitric oxide and other NO species is lower than in wild-type

cardiovascular system
• percentage of smooth muscle area in all arteries is greater in hph1-deficient mice compared to controls with no change in lumen size with fewer non muscular vessels and more partially or fully muscular vessels in mutants
• there is more smooth muscle area in arteries associated with alveolar ducts compared to other arteries in mutants or controls
• the RV:LV + S ratio is higher in mutants; this is entirely due to the enlarged right ventricle as seen when indexed to body weight
• right ventricular pressure is significantly increased vs controls

respiratory system
• there is more smooth muscle area in arteries associated with alveolar ducts compared to other arteries in mutants or controls

digestive/alimentary system
• mutants have smaller, more distended stomachs than control: diameter of the pylorus is smaller than control

muscle
• pylorus has disproportionately thicker longitudinal, circular and muscularis mucosae layers than in wild-type mice; the hypertrophy begins ~age 10 days and is resolved by 180 days of age
