Genomic Structure of the Human GLUT9 Gene
(A) The structure of the GLUT9 gene and cDNAs. The human GLUT9 gene contains 14 exons (1 noncoding and 13 coding) and is located on chromosome 4p15.3-p16. The alternative splicing of the GLUT9 gene results in two main transcripts: GLUT9 isoform 1 (long isoform, GLUT9L) and isoform 2 (short isoform, GLUT9S).
(B) Exon-intron boundaries of the GLUT9 gene.
