Figure 4. Pedigree of the family ARRP-49 and mutations identified by Sanger sequencing analysis.
A shows the segregation of compound heterozygous changes c.8422G>A (MU1) and c.7868G>A (MU2). Genotypes are presented as follows: MU1/MU2 represents individuals with both mutations as compound heterozygous; MU1/+ and +/MU2 indicate heterozygous carriers; +/+ indicates individuals carrying two wild-type alleles. NA denotes DNA samples that were unavailable.
