Figure 1 (A) Genomic sequence of the mother showing a heterozygous FGFR1 mutation c.2049-1 G → C in intron 15. (B) Agarose gel electrophoresis of FGFR1 cDNA PCR products. A 750–800 bp band (arrow, lane 2) was amplified from the cDNA synthesized from the peripheral blood lymphocyte RNA of the mother (lane 2). This band was not amplified from the cDNA derived from the control subject negative for this mutation (lane 3). Lane 1, size marker 100 bp ladder (GeneRuler, Fermentas, Ontario, Canada). (C) cDNA sequence demonstrating skipping of the exon 16.
