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]

The c.917C>A (p.S306Y) alteration is located in exon 7 (coding exon 7) of the CLMP gene. This alteration results from a C to A substitution at nucleotide position 917, causing the serine (S) at amino acid position 306 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
