Figure 4. Partial sequences of NDP exon 3 from the ND patient III:5 (A; homozygous for the c.343C>T genotype), carrier III:6 (B; heterozygous for the genotype), and control (C). The black arrows show the mutation CGA > TGA in the proband and a carrier, altered the arginine codon to a termination codon, but this mutation was not found in normal controls.
