Fig. 2 Examples of PCR-SSCP and heteroduplex (hdx) analyses of the JAGGED1 gene. (A) Exon 13: normal pattern (lanes 1 and 3) and A131r pattern with a delCT (lane 2). (B) Exon 17: normal pattern (lanes 1, 3, and 5), A8r pattern with an insA (lane 2), and A11r pattern with a delCAGT (lane 4). (C) Exon 9 patterns: affected father with a C>T (lane 1), propositus A28r with a C>T (lane 2), and unaffected mother (lane 3).

Fig. 3 Distribution of the 117 JAGGED1 mutations14-17 (including this study) in the 26 exons of the gene. ▩, Cases reported in the present study. The signal peptide is encoded by part of exon 1 and the DSL domain by part of exon 4, the 16 EGF-like repeats correspond to exons 5–21, the cysteine-rich region partially overlaps exons 22–24, and the transmembrane domain and the intracellular region are encoded by exon 26.
