Minigene assays. (A) Scheme of the different minigene constructs for the exon 12, 14, 15–16 and exon 17 genomic regions. (B,C) PCR products of the minigene constructs obtained using SA and SD primers inside pSPL3 vector. MW: DNA Molecular Weight VI (Roche). V1 and V2 denote the artificial exons of the pSPL3 vector. The sizes of the PCR products are shown on the right. In B) lanes 1 and 2 show the PCR products of the constructs carrying exon 12 wild type (lane 1) and c.1107G > T (Glu369Asp) (lane 2), exon 15–16 wild type (lane 3), c.1282 -1G > A (lane 4), exon 17 wild type (lane 5) and c.1601C > G (Ser534*)(lane 6). Ex12, Ex15, Ex16, Ex17 and Ex16* of EYA4 gene denote exons 12, 15, 16, 17 and 16 lacking the first 68 pb, respectively. In C) lanes 1 and 2 show the PCR products of the empty vector (263 bp) and the RT negative control, respectively. Lane 3 shows a dramatic reduction in the intensity of the 352pb band and the presence of supernumerary bands.
