Genes affected
NMB (HGNC:7842): (neuromedin B) This gene encodes a member of the bombesin-like family of neuropeptides, which negatively regulate eating behavior. The encoded protein may regulate colonic smooth muscle contraction through binding to its cognate receptor, the neuromedin B receptor (NMBR). Polymorphisms of this gene may be associated with hunger, weight gain and obesity. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2015]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 04, 2024The c.151G>A (p.A51T) alteration is located in exon 1 (coding exon 1) of the NMB gene. This alteration results from a G to A substitution at nucleotide position 151, causing the alanine (A) at amino acid position 51 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
