Given that the cause of the disorder is an enzyme deficiency (see Clinical features below), it is reasonable to assume autosomal recessive inheritance. `\n- `Clin feat: The initial report (Valle et al., 1981) described an adult male, domestic shorthaired cat of uncertain age and ancestry that . . . was presented for evaluation of suspected blindness and was found to have bilateral generalized retinal atrophy. Retinal thinning and vascular attenuation were present diffusely over both fundi. Amino-acid screening of his urine revealed ornithinuria. Consistent with this observation, Valle et al. (1981) reported undetectable levels of the enzyme ornithine aminotransferase (OAT), which is indicative of gyrate atrophy of the choroid and retina.`\n- `Defect: yes`\n## Evidence (references)\nDerived from OMIA database dump (omia.xml, local); structured field, not verbatim prose.\n- 1989.
