3. Kawasaki disease(English)

   • an acute febrile pediatric vasculitis affecting small- to medium-sized vessels (including coronary arteries) and the leading cause of acquired heart disease in children in the United States. Gastrointestinal symptoms are often reported during the acute phase of the disease. The gastrointestinal tract is home to trillions of microorganisms, collectively known as the intestinal microbiota

5. Kennedy disease(English)

   • a rare, adult-onset, X-linked recessive neuromuscular disease caused by CAG expansions in exon 1 of the androgen receptor gene. The diagnostic possibility is typically raised when an adult man presents with slowly progressive lower motor neuron symptoms associated with signs of androgenic dysfunction such as gynecomastia. The genetic cause is an abnormal expansion of CAG repeats in exon 1 on androgen receptor AR gene located on chromosome X at position q11–12; aka Kennedy's syndrome, SBMA
