In 2014, Chetaille et al. described chronic atrial and intestinal dysrhythmia (CAID) syndrome associated with a recessive SGO1 mutation (p.Lys23Glu) linking it to both intestinal pseudo\u2010obstruction and cardiac dysrhythmia. This study aimed to describe the clinical and nutritional features and outcomes of pediatric patients with the homozygous SGO1 (p.Lys23Glu) mutation.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We retrospectively enrolled children under 18 years with PIPO and homozygous (p.Lys23Glu) SGO1 mutation.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Eight patients were included (five girls), two were first\u2010degree relatives. All exhibited a typical PIPO clinical presentation, but with a later onset than usually seen in primary PIPO (median age: 6.3 years). Contrast studies revealed massively distended small bowel and colon in all patients. Antroduodenal and\/or colonic manometry, performed in six patients, revealed a neuropathic pattern. A full\u2010thickness intestinal biopsy showed variable fibrosis of the smooth muscle internal layer associated with an abnormal presence of Cajal cells within the muscular layers. All patients required parenteral nutrition (PN) at a median age of 11.8 years. Five patients needed an ileostomy. At 18 years, one patient was off PN. Three patients developed sinus dysfunction: one at the time of PIPO diagnosis and two later. All required pacemakers. One patient died in her twenties secondary to cardiac complications.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Recessive SGO1 mutation is a form of late onset PIPO associated with sinus dysfunction. Long\u2010term outcome is unclear.
