- OMIA molecular-genetics note: By sequencing an obvious candidate gene (F9), Goree et al. (2005) reported different causative mutations in two affected cats: "Affected cat 1 had a single nucleotide change in exon 8 at the 1st nucleotide position of the codon encoding an arginine (CGA to TGA) at amino acid position 338 [omia.variant:310]. This mutation would be predicted to result in the appearance of a premature stop codon in t…
