Figure 3. Genomic organization showing the region of R77S mutation. Electropherogram showing C>A heterozygous transversion in exon 2 CRYGD. The comparison of wild type and mutant sequences show c.229C>A substitution changes amino acid arginine to serine at position 77 (first amino acid is methionine). The dotted block shows the site of mutation and circle depicts the altered amino acid.
