Abstract

Congenital short-bowel syndrome (CSBS) is a rare neonatal pathology associated with poor prognosis and high mortality rate. We describe a newborn presenting CSBS intestinal malrotation and chronic intestinal pseudo-obstruction syndrome (CIPS), compound heterozygous for two previously unreported heterozygous mutations in Coxsackie and adenovirus receptor-like membrane protein (CLMP) gene, one in intron 1 (c.28+1G>C), the other on exon 4 (c502C>T, p.R168X). Both mutations are predicted to be pathogenic, leading to impaired splicing and the appearance of a premature stop codon, respectively. Our case is remarkable in that it concerns two heterozygous truncating mutations associated with a good clinical prognosis with a favorable cerebral and gastrointestinal outcome and a substantial enteral input at 8 months of age, despite a small intestine measuring only 35cm.
