Genes affected

NTSR1 (HGNC:8039): (neurotensin receptor 1) Neurotensin receptor 1 belongs to the large superfamily of G-protein coupled receptors. NTSR1 mediates the multiple functions of neurotensin, such as hypotension, hyperglycemia, hypothermia, antinociception, and regulation of intestinal motility and secretion.

The c.644A>G (p.D215G) alteration is located in exon 1 (coding exon 1) of the NTSR1 gene. This alteration results from a A to G substitution at nucleotide position 644, causing the aspartic acid (D) at amino acid position 215 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
