Genomic DNA sequencing chromatograms of small regions of exons 8 and 10 of the SLC3A1 gene from a healthy and cystinuric cat. (A) Homozygous missense mutation (arrow) in the cystinuric cat. This single nucleotide substitution in exon 8 is unique to the cystinuric cat and is predicted to change the amino acid from arginine (Arg) to tryptophan (Trp). (B) Homozygous missense polymorphism. This single nucleotide substitution in exon 10 is predicted to change the amino acid from isoleucine (Ile) to valine (Val) and was seen in both cystinuric and healthy cats.
