When is it used?

  • Used in lab systems, EHRs, and clinical data exchange.
  • May identify a test, observation, survey item, or clinical document request rather than a diagnosis.
  • Status: ACTIVE
  • Order vs observation: Observation
  • Method: Molgen

What it does not mean

  • The code identifies the observation or test, not the actual result.

Key facts

ANKK1 gene c.2137G>A [Genotype] in Blood or Tissue by Molecular genetics method Nominal
ANKK1 gene.c.2137G>A
The patient's genotype for the DRD2/ANKK1 Taq1A polymorphism (rs1800497, Glu713Lys, c.2137G>A) variant in the ANKK1 (Ankyrin repeat and kinase domain containing 1) gene. This variant is associated with reduced striatal D2/3 receptor binding in healthy individuals as well as depression and addiction.[PMID23683269]
