dbSNP Column Description for table: RsMergeArch

Table name and description
Beginning in 2018, dbSNP will no longer provide relational database table dumps on the FTP site or any general SQL support for future build releases (see announcement).

Table Description
"refSNP(rs) cluster is based on unique genome position. On new genome assembly, previously different contig may align. So different rs clusters map to the same location. In this case, we merge the rs. This table tracks this merging."

Table column and description

Column Description Type Byte Order
rsHigh Since rs# is assigned sequentially. Low number means the rs occurs early. So we always merge high rs number into low rs number. int 4 1
rsLow int 4 2
build_id dbSNP build id when this rsHigh was merged into rsLow. smallint 2 3
orien The orientation between rsHigh and rsLow. tinyint 1 4
create_time smalldatetime 4 5
last_updated_time smalldatetime 4 6
rsCurrent rsCurrent is the current rs for rsHigh. If rs9 is merged into rs5 which is later merged into rs2, then rsCurrent is 2 for rsHigh=9. int 4 7
orien2Current tinyint 1 8
