Five distinct noveltranscripts (RES4-22, -23, -24, -25 and -26) that mapped to the 1-Mb interval between D4S180 and D4S183 on human chromosome 4p16.3 close to the Huntington's disease (HD) gene were isolated, and the structure and exon/intron organization of each gene were thoroughly analyzed. The transcripts of the RES4-22, -23 and -24 genes each have several isoforms by alternative splicing and these have also been defined. Two transcripts, RES4-24 and RES4-25, reside in the same genomic region with opposite polarities and they also clearly overlap. Among these transcripts, RES4-26 was found to encode a novel zinc finger protein. The transcript map based upon our current level of analysis combined with data from previous studies reveals the gene-rich nature and the intricate organization of the genes in the HD locus.
