Figure 2. Confirmatory NRL sequence analysis. Chromatograms of the NRL sequence variants from a normal control individual and affected subjects, IV:2 from family MM1 (A), II:6 from family RP-3051 (B) and II:1 from family RP-1553 (C). Note that homozygous mutations c.713G>T in family MM1, c.238C>T in family RP-3051 and c.544C>T in family RP-1553 are shown.
