Genes affected

NMBR (HGNC:7843): (neuromedin B receptor) This gene encodes a 7-transmembrane G protein-coupled receptor that binds neuromedin B, which is a growth factor and mitogen for gastrointestinal epithelial tissue and for normal and neoplastic lung. This receptor may play a role in smooth muscle contraction, neuronal responses, and the regulation of cell growth. Antagonists of this receptor have a potential therapeutic use in inhibiting tumor cell growth. Polymorphisms in this gene may be associated with a susceptibility for schizophrenia. Alternative splicing of this gene results in multiple transcript variants. [provided by RefSeq, Apr 2016]

The c.382G>A (p.G128R) alteration is located in exon 1 (coding exon 1) of the NMBR gene. This alteration results from a G to A substitution at nucleotide position 382, causing the glycine (G) at amino acid position 128 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
