We categorized the 65 GABAB1 splice junctions into four groups: 22 known, 5 known-alternative, 8 partial-novel, and 30 novel splice junctions (Figure S2 in Supplement 1). The known splice junctions represent those found in the RefSeq Genes model. The known-alternative splice junctions represent different splicing site combinations of the known splice junctions. The partial-novel splice junctions represent junctions with one known splicing site and another unknown site. The novel splice junctions represent junctions where both splicing sites are unknown.
