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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 09, 2023The c.65C>T (p.A22V) alteration is located in exon 1 (coding exon 1) of the NTSR1 gene. This alteration results from a C to T substitution at nucleotide position 65, causing the alanine (A) at amino acid position 22 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
