Variations for which there is not yet an enumerated clinical significance class. These variations are grouped in a clinical significance class called "other", which includes: Variations* that are found only in somatic cells and are with or without known trait of phenotype; Somatic or germline variations that are disease risk factors; Somatic or germline variations that act to protect a disease state (protective variants)

*

Note: If a variant's source is not asserted during submission, dbSNP assumes that the source of the variant is germline. Those variants submitted with the clinical phrase (clinic_phrase) tag set to "cancer" are reported as somatic.

Note: As assertion categories may change, see ClinVar for up-to-date clinical assertion definitions.

Note: The clinical significance terms presented in table 5 are based on terminology recommended by the American College of Medical Genetics and Genomics (ACMG). ACMG revisions are adopted by NCBI as quickly as possible. See http://www​.ncbi.nlm.nih​.gov/clinvar/docs/clinsig/#standard for the most recent clinical significance terms used in NCBI’s reporting.
