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.569A>G (p.H190R) alteration is located in exon 1 (coding exon 1) of the NMUR2 gene. This alteration results from a A to G substitution at nucleotide position 569, causing the histidine (H) at amino acid position 190 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
