Organization of alternative U exon-containing transcripts. The first four splice variants were identified by RT–PCR analysis of brain RNA (small horizontal arrows designate the position of oligonucleotide primers used in these experiments. EST clones are designated by the GenBank accession number. The ESTs designated by the asterisk are the 5′- and 3′ ESTs of clone 9330122E19 that has not been fully sequenced as indicated by the dashed line. The U-Snurf/Snrpn EST from rat (GenBank accession no. CB585841) is arbitrarily represented relative to the mouse upstream region. The extent of the 35 kb ΔPWS-IC is indicated by the solid horizontal line. Not drawn to scale.
