Figure 6. A high-resolution, melt curve analysis (HRM) for the mutation c.6249delT (p. I2084fs) in family F6. In the amplicon, there is a SNP rs6657250, c.6317T>C, as marked in the plot. A: A difference plot for the five members in family F6. The median green, straight line presents the normal control with c.6317T>C. The real-time PCR products of the family members are compared to the median normal control to produce the plot. The curve revealed that the mutant pattern (area within the rectangle) co-segregated with the affected individuals 073001, 073004, and carriers, 073003, but not with the unaffected individuals 073002, 073005, and normal controls c.6317T/T or c.6317C/C. B: Direct sequencing analysis shows the heterozygous, one-base-deletion mutation c.6249delT (p.I2084fs) in patients 073001 and 073004 and in the carrier 073003; sequences in individuals 073002 and 073005 are the wild type.
