phenotype observed in females
phenotype observed in males
N normal phenotype
• arterial pH is significantly reduced
• serum bicarbonate is significantly reduced
• acid loading by adding ammonium chloride to drinking water leads to a further drop on serum bicarbonate
• elevation of serum TSH after P14
• mice show decreased intrathyroidal concentrations of both thyroglobulin-bound and free thyroid hormones (T4 and T3) suggesting defective thyroglobulin iodination and thyroid hormone biosynthesis rather than impaired secretion
• reduction of T4 is more severe than of T3
• low serum T4 levels at P14

endocrine/exocrine glands
• thyroid shows enlarged follicles with excess colloid lined by normal or tall follicular epithelium
• goiter is evident from P14 onwards, with 1.7-fold increase in thyroid weight at P14 and 21.5-fold increase at P90
• mice are hypothyroid
• males supplemented with 30 ug iodide/day show partial reversal of hypothyroidism, with reduced TSH and increased T3 levels, and after 6 weeks of treatment, TSH and T3, but not T4, levels are comparable to controls

renal/urinary system

digestive/alimentary system
• gastric acid secretion significantly reduced (46 mEq/g vs 75 mEq/g for controls)
