Identification of the novel mutation in the PKD1 gene. a Direct sequencing revealed a heterozygous splice mutation (c.2854-3C > G) in inton11. a1: DNA sequence of the patients, a2: DNA sequence of the healthy controls, b Direct mRNA sequencing, b1: Agarose gel electrophoresis for RT-PCR. b2: mRNA sequence of the patients. b3: mRNA sequence of the healthy controls. c The confirmation of transcription by the TA clone. c1:The normal patients’ isoforms by TA cloning. c2: The mutant patients’ isoforms by TA cloning. d The patients’ frameshift mutation. ★-mutant base and ▲-inserted bases. Samples of patients and controls were tested under the same conditions, including equal amounts of sample (peripheral blood and RNA) and experimental conditions
