FYCO1 Frameshift Deletion in Wirehaired Pointing Griffon Dogs with Juvenile Cataract
Different breed-specific inherited cataracts have been described in dogs. In this study, we investigated an inbred family of Wirehaired Pointing Griffon dogs in which three offspring were affected by juvenile cataract. The pedigree suggested monogenic autosomal recessive inheritance of the trait. Wh...
