Fig. 2From: SLC4A4 compound heterozygous mutations in exon–intron boundary regions presenting with severe proximal renal tubular acidosis and extrarenal symptoms coexisting with Turner’s syndrome: a case reportModels of aberrant transcription caused by splice site mutations. Models of exon skipping by c.1076 + 3A > C mutation (a) and c.1772-2A > T mutation (b) are shown. Alternatively, models of intron retention and activation of cryptic splice sites by c.1076 + 3A > C mutation (c) and c.1772-2A > T mutation (d) are shown. Cryptic splice sites are predicted using Splice Site Prediction by Neural Network in Berkeley Drosophila Genome Project. All the four models predict premature stop codonsBack to article page
