Qualifier	allele
Definition	name of the allele for the given gene
Value Format	"free text"
Example	<INSDQualifier_value>adh1-1</INSDQualifier_value>
Comment	all gene-related features (exon, CDS etc) for a given gene should share the same allele qualifier value; the allele qualifier value must, by definition, be different from the gene qualifier value; when used with the variation feature key, the allele qualifier value should be that of the variant.
