Validation status codes summarize available validation data

Validation evidenceDescriptionCode in database for ss#Code in FTP dumps for ss#Code in database for rs#Code in FTP dumps for rs#
Not ValidatedValidation code for an ss, where there is no BatchUpdate information, no 0 or 1 frequency data, and no non-computational validation method.
Validation code for an rs, ""or""ed from ss code. If the rs has single ss with code 1, then the rs code is set to 0.
0Not present0aNot present
By ClusterValidation code for an rs that has at least two ss, and at least one of those ss was validated by a non-computational method.
Validation code for an ss, if the method is non-computational.
Validation code for a single member rs where the ss validation_status is 1, the rs validation_status is set to 0.
11b1,0b1
By FrequencyValidation code for a variation that has frequency or genotype data and has a minor allele count of at least 2.2222
By SubmitterValidation code for a variation that had a BatchUpdate with a second validation method submitted by the original submitter.4444
by DoubleHitValidation code for a variation where every allele has been observed in at least two chromosomes.8888
HapMapValidation code for a variation that has genotype frequency from HapMap.16161616

a) If the rs# has a single ss# with code 1, then rs# is set to code 0. b) For a single member rs where the ss# validation status = 1, the rs# validation status is set to 0.

Note: 57 Additional validation codes defined by bitstring are available in the SNPValidationClass file, location in the shared​_data directory of the dbSNP FTP site.
