Abstract
Congenital short bowel syndrome (CSBS) is a rare condition characterized by an inborn shortening of bowel length with loss of intestinal functions, which often combines malrotation. CXADR-like membrane protein (CLMP) and filamin A (FLNA) gene mutations are the two major causes of this inherited defect. We presented two siblings with the older brother suffering from a laparotomy for bowel obstruction due to malrotation on the 17th day after birth. The younger sister encountered a laparotomy for lactobezoar at 6 months old. CSBS was diagnosed by measurement of the bowel length during the operations. Compound heterozygous CLMP mutations with the paternal allele harboring a long deletion across exon 3-5 and the maternal allele bearing a non-sense mutation of exon 3 (c.235C > T, p.Q79∗) were identified in both cases. They are the first reported familial CSBS caused by novel CLMP mutations in Taiwan.

Abstract
Objective: To describe the clinical presentation and novel mutation in the coxsackie and adenovirus receptor-like membrane protein (CLMP) gene in a Chinese family with congenital short bowel syndrome (CSBS). Methods: We collected clinical data from a Chinese family with inherited CSBS, and performed whole exon sequencing of the children and their parents. The pathogenic sites of candidate genes were targeted, and the detected exon deletions were verified by quantitative PCR. Results: Two siblings in this family presented with bilious vomiting, and were diagnosed with CSBS on laparotomy. Two siblings and their parents underwent complete exome sequencing of the peripheral blood. Both children had CLMP gene exons 3-5 homozygous deletion mutation, while the parents had a heterozygous mutation. Conclusion: This study identified a novel mutation of the CLMP gene in a Chinese family with CSBS. Identification of this mutation can help with genetic counseling and prenatal diagnosis of CSBS.

Abstract
Congenital short bowel syndrome (CSBS) is a rare congenital neonatal disorder. CSBS results from intestinal impairment during embryogenesis. Mutated CXADR-like membrane protein ( CLMP ) and Filamin A genes are involved in the cause of CSBS. In this study, due to our misdiagnosis, we had to perform whole exome sequencing on the patient, and also we implemented cosegregation analysis on his parents with consanguineous marriage and also parents' mothers. We identified a homozygous loss of function mutation in the CLMP gene in exon 5 (c.664C > T, p.R222X). Also, both parents and grandmothers of the proband were heterozygous for this mutation. Loss of function mutation in CLMP causes CSBS, leading to impaired intestinal development.
