Figure 2. Chromatograms showing the variants detected in the canine DFNB31 gene (exon 3). c.970G>A and c.985G>A result in a substitution of valine for isoleucine at position 324 and alanine for threonine at position 329 of DFNB31, respectively (top). c.978T>C does not result in a change in the amino acid sequence (bottom). In both chromatograms, the relevant area is marked with an arrow.
