referenceBases	Reference 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 be used as a standalone base of any type or within a partially known sequence. As example, a query of ANNT the Ns can take take any form of [ACGT] and will match ANNT, ACNT, ACCT, ACGT ... and so forth. an empty value* is used in the case of insertions with the maximally trimmed, inserted sequence being indicated in AlternateBases.NOTE: Beacon instances may not support UIPAC codes and it is not mandatory for them to do so. In such cases the use of [ACGTN] is mandated.	string	NA	A, T, N, , ACG	NA
