PharmGKB Schema Documentation: <variant>

pharmgkbId	A unique identifier assigned by the PharmGKB (the PharmGKB Accession Id). This attribute is used to refer to data that is already in the PharmGKB and is only supplied when editing or adding to such data. See the FAQ for details.
localId	A unique identifier for this element assigned by the submitter. The only rule it must follow is that no two XML elements can be assigned the same localId within a single XML document. See the FAQ for details.

note	A note.
submitter	This element's submitter.
position	The position on the reference sequence where this variant is found.
allele	The allele found on a chromosome. The allele sequence must be composed of `A`'s, `G`'s, `C`'s, `T`'s, and `-`'s (to denote a deletion). For repeats, the repeated bases should be enclosed within parentheses followed by the number of times the sequence is repeated (e.g. `(AT)6`). If the polymorphism spans multiple bases and is not an insert, then the bases should be enclosed within square brackets (e.g. `[ATC]`). See the FAQ for details.
xref	A cross-reference to a resource with more information on this variant.

Content validation performed on this element:

The position must lie on the reference sequence and at least 25 bases from the end of the sequence.
If the variant is reported in a PCR or sequencing result, the position must also lie in an interrogatedRange. If no interrogated range is specified, it must lie on either the amplicon (if the assay performed was a PCR assay) or analyzedRegion (if the assay performed was a sequencing assay).
If the variant is reported in a PCR or sequencing result, the reference sequence base at the position must be an A, C, T, or G.
If the variant is reported in a genotyping result, the position must be the same as the interrogatedPosition of the assay that was performed.
There must not be a genotypeInSampleSet defined at the same position within the experiment in which this variant is reported.
