What is this code?

LOINC codes identify tests, measurements, observations, survey items, and clinical questions in a standardized way. It is associated with the component GJB3 gene targeted mutation analysis. It is commonly used with the system or sample type Bld/Tiss.

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: Both
  • Method: Molgen

What it does not mean

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

Key facts

GJB3 gene targeted mutation analysis in Blood or Tissue by Molecular genetics method
GJB3 gene targeted mutation analysis
Multiple variants or mutations within the gap junction protein, beta 3 (GJB3) gene are associated with Sensorineural Hearing Loss (SNHL). This term was created for, but not limited to, Asper Biotech's Sensorineural Hearing Loss (SNHL) microarray test. This test is a targeted mutation analysis for the following variants with the GJB3 genec.421A>G (rs74315320), c.421_423delATT, c.538C>T (rs74315319), c.547G>A (rs74315318), and c.667C>A.
