Genes affected

CLMP (HGNC:24039): (CXADR like membrane protein) This gene encodes a type I transmembrane protein that is localized to junctional complexes between endothelial and epithelial cells and may have a role in cell-cell adhesion. Expression of this gene in white adipose tissue is implicated in adipocyte maturation and development of obesity. This gene is also essential for normal intestinal development and mutations in the gene are associated with congenital short bowel syndrome. [provided by RefSeq, Aug 2015]

CLMP Gene-Disease associations (from GenCC):

• congenital short bowel syndrome, autosomal recessive
