A statement (assertion) based on experimental evidence that a variant is located at a particular position. Since asserted positions are based on experimental evidence, they cannot be seen as a conformation of the variant’s position even if there are multiple claims by different submitters of a specific position for a particular variant.

NCBI does not independently verify assertions and cannot endorse their accuracy.

Note: Submissions based on asserted positions should reference a sequence accession that is part of an assembly represented in the NCBI Assembly Resource. If no assembly is available however, the reference sequence can be an INSDC sequence accession. If a submission asserts a position for a variation using an accession that cannot be aligned to an assembly, the rs for that variation cannot be annotated to the human assembly, and therefore will not appear on maps or graphic representations of the assembly.
