Characterization of the new CLCN5 5′UTR long transcripts by RACE PCR and sequencing. The four long transcripts contain the already described exons I-IV and the new exons V and VI (variants 8-11) (131 bp and 194 bp long, respectively), located 7820 bp and 11977 bp downstream of the exon IV respectively . + 1 indicates the putative transcriptional start site located at nucleotide - 660 in respect to the ATG initiation codon in exon III. Coloured boxes represent exons and open boxes represent introns.
