||Alternate bases for this variant (starting from
start). Accepted values: IUPAC codes for nucleotides (e.g. 'https://www.bioinformatics.org/sms/iupac.html'). N is a wildcard, that denotes the position of any base, and can beused as a standalone base of any type or within a partially knownsequence. As example, a query of
ANNT the Ns can take take any form of[ACGT] and will match
ACGT ... and so forth. an empty value is used in the case of deletions with the maximally trimmed, deleted sequence being indicated in
ReferenceBases Categorical variant queries, e.g. such not being represented through sequence & position, make use of the
variantType parameter. either
variantType is required.
