## Intersection of http://hl7.org/fhir/uv/genomics-reporting/CodeSystem/pharmgkb-evidence-level-custom-cs and http://hl7.org/fhir/uv/genomics-reporting/CodeSystem/pharmgkb-evidence-level-custom-cs

This is the CodeSystem that contains codes in both PharmGKB Evidence Level Example Codes (http://hl7.org/fhir/uv/genomics-reporting/CodeSystem/pharmgkb-evidence-level-custom-cs) and PharmGKB Evidence Level Example Codes (http://hl7.org/fhir/uv/genomics-reporting/CodeSystem/pharmgkb-evidence-level-custom-cs).

This code system `http://hl7.org/fhir/comparison/CodeSystem/2c33a04b-40d2-467e-a11c-0ae64722db95-27` defines codes, but no codes are represented here

Code | Display | Definition
1A | PGKB 1A | High level of evidence. Supported by a guideline or FDA label with variant specific prescribing guidance. Additionally, supported by at least one publication.
1B | PGKB 1B | High level of evidence. But, NOT supported by a guideline or FDA label with variant specific prescribing guidance. Additionally, supported by at least one publication.
2A | PGKB 2A | Moderate level of evidence. Supported by being a KNOWN pharmacogene on https://www.pharmgkb.org/vips. Also, found in multiple studies but may have a minority of studies that did not support the majority opinion. Supported by at least two indpendent publications.
2B | PGKB 2B | Moderate level of evidence. NOT in the list of very important, KNOWN pharmacogenes. Found in multiple studies but may have a minority of studies that did not support the majority opinion. Supported by at least two indpendent publications.
3 | PGKB 3 | Low-level of evidence. Where either the assocation is based on a single study, failed to be reproduced, or preliminary evidence.
4 | PGKB 4 | The evidence does not support an association between the variant and the drug phenotype. (negative)
