Please review OMIA for other variants. Information relating to PRA due to a variant in the CNGB1 gene was previously listed here but has been moved to 'OMIA:002723-9615 : Retinal atrophy, progressive, CNGB1-related in Canis lupus familiaris' [16/06/2023].`\n## Associated gene(s)\nDerived from OMIA database dump (omia.xml, local); structured field, not verbatim prose. First-hand values below are verbatim substrings of the topic's pdf-raw/omia/<phene_id>.txt source file.\n- OMIA molecular-genetics note: Extensive molecular investigations have excluded the opsin gene as a candidate locus for this disorder in Miniature Poodles, English Cocker Spaniels or Labrador Retrievers (Gould et al., 1995).\n\n## Evidence (references)\nDerived from OMIA database dump (omia.xml, local); structured field, not verbatim prose.
