In this latter case, the novel mutation was present in compound heterozygosis with p.Glu442Gly. [journals.plos.org]

Two distinct clinical presentations are described: antenatal form and “classical” form. [nature.com]

• Fatigue

  Bartter described this syndrome in two African-American patients: a 5 year old boy and a 25 year old man with a long history of slow growth, weakness and fatigue. [flipper.diff.org]

  Manifestations vary depending on genotype, but growth and development may be affected and electrolyte abnormalities may cause muscle weakness, cramping, spasms, tetany, or fatigue. [merckmanuals.com]

  Symptoms Symptoms of Bartter syndrome may include: generalized weakness and fatigue increased urination (polyuria) increased thirst (polydipsia) waking up at night to urinate (nocturia) mild dehydration craving salt muscle cramping constipation Children [verywell.com]

  Low blood levels of potassium can cause muscle weakness, cramping, and fatigue. Continued Diagnosis and Treatment For children with symptoms of classic Bartter syndrome, a doctor will do a thorough exam along with blood and urine tests. [webmd.com]

• Weight Loss

  Following birth, neonate should be monitored for urine output, hydration, weight loss, and electrolyte balance. Correction of dehydration and electrolyte imbalance are the important aspects of management. [hindawi.com]

  Neonates suspect for Bartter syndrome should be monitored closely for urine output, hydration status, weight loss and electrolyte balance. The characteristic electrolyte abnormalities include hypokalemia and metabolic alkalosis. [nature.com]

  Finally, I will emphasize the diagnosis of anorexia nervosa can be elusive, because in contrast to most patients with loss of weight for other medical conditions (i.e. hyperthyroidism malignancy etc.) who express concern over their weight loss or alterations [omicsonline.org]
