Genes affected

NMUR2 (HGNC:16454): (neuromedin U receptor 2) This gene encodes a protein from the G-protein coupled receptor 1 family. This protein is a receptor for neuromedin U, which is a neuropeptide that is widely distributed in the gut and central nervous system. This receptor plays an important role in the regulation of food intake and body weight. [provided by RefSeq, Jul 2008]

Collection Method: clinical testing

The c.1208C>T (p.S403L) alteration is located in exon 4 (coding exon 4) of the NMUR2 gene. This alteration results from a C to T substitution at nucleotide position 1208, causing the serine (S) at amino acid position 403 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
