Figure 5. A portion of GJA3 DNA sequence in an affected and an unaffected individual

A: DNA sequence electropherogram (forward strand) showing the heterozygous 98G>T transversion that replaces arginine by leucine at codon 33 in the affected individual (2-7). B: DNA sequence electropherogram of an unaffected individual (2-1) showing wild type G at position 98. The position of mutated (G>T) and wild type nucleotide G in an affected and an unaffected individual (2-7 and 2-1, respectively) is indicated with pink arrows.
