idiopathic congenital intestinal pseudo-obstruction

Monday 4 April 2005

Chronic idiopathic intestinal pseudoobstruction (CIIP) is caused by severe abnormality of gastrointestinal motility.


- primary CIIP (defects of enteric neuronal cells)

  • autosomal recessive inheritance
    • syndrome associating short small bowel, malrotation, and pyloric hypertrophy associated with morphologic defects of argyrophil neurons in the myenteric plexus (MIM.243180)
  • X-linked inheritance
    • L1CAM germline mutations at Xq28

- secondary CIIP

  • Chagas disease
  • myxedema
  • Duchenne muscular dystrophy


- hydrocephalus with stenosis of the aqueduct of Sylvius (HSAS) (15368500)

  • germline mutations of the L1CAM coding for L1 cell adhesion molecule at Xq28 (15368500)
