Recommended genetic screening by breed

Some dog and cat breeds have genetic predispositions to hereditary diseases. Genetic testing allows us to detect these conditions early and adapt medical care accordingly.

We may recommend these screenings during your pet’s paediatric health check when it is relevant for their breed.

If your companion’s breed does not appear in the list, feel free to mention it during your consultation.

Dog breeds

  • CEA A hereditary eye condition that can lead to retinal abnormalities. Variable severity.
  • Mucopolysaccharidosis VII A rare metabolic disease causing weakness, stunted growth and progressive deterioration. Serious course.
  • Eye anomaly in the Collie (CEA) A congenital malformation of the retina, sometimes silent, which can lead to reduced vision.
  • MDR1 Mutation causing a high sensitivity to certain drugs (antiparasitics, analgesics, etc.). Risk of severe toxicity.
  • Blackbird gene Useful in breeding to avoid double-merle puppies (risk of deafness and eye deformities).
  • CEA Congenital retinal malformation, fairly common in the breed.
  • MDR1 A frequent mutation causing severe drug sensitivity.
  • Blackbird gene Essential screening to avoid double-merle marriages.
  • Blackbird gene Only for merle lines. Auditory and ocular risks in the case of double merle.
  • CEA A common hereditary eye condition.
  • MDR1 common mutation resulting in drug sensitivity.
  • Type 3 von Willebrand disease Severe coagulation disorder (rare).
  • Blackbird gene Useful for reproduction.
  • CEA relatively common; possible retinal anomalies.
  • Blackbird gene Useful for breeding to avoid double-merle.
  • Progressive retinal atrophy (PRA) progressive degeneration of photoreceptors leading to blindness.
  • Type 1 von Willebrand disease moderate coagulation disorder which may cause prolonged bleeding.
  • Krabbe disease Severe neurological disease due to toxic accumulation in the nervous system. Rapidly fatal course.
  • Progressive retinal atrophy (PRA) Progressive loss of vision (night → day).
  • Type 1 von Willebrand disease : tendency to mild to moderate bleeding.
  • Blackbird gene Screening only useful for merle lines.
  • Familial nephropathy A serious hereditary kidney disease of young dogs.
  • PRA Hereditary progressive blindness.
  • PFK deficiency intolerance to exertion and episodes of weakness.
  • CEA Very common; hereditary retinal dysplasia.
  • MDR1 Widespread mutation → high drug risk.
  • PRA-rcd2 hereditary retinal degeneration.
  • Blackbird gene : useful depending on the dress.
  • PRA Hereditary progressive blindness.
  • PFK deficiency Possible depending on lineage (intolerance to exercise).
  • PRA A hereditary eye disease that can appear late in life.
  • Gangliosidosis GM1 severe neurodegenerative disease causing loss of motor and sensory functions.
  • PRA From Poodle / Retriever bloodlines.
  • PRA Progressive blindness (loss of vision at night, then during the day).
  • CNM Myopathy hereditary muscle weakness.
  • Pyruvate kinase deficiency chronic haemolytic anaemia.
  • Blackbird gene Only for merle lines (auditory/ocular risks in double merle).
  • Blackbird gene Useful for reproduction.
  • CEA hereditary retinal malformation.
  • PRA progressive blindness according to lineage.
  • PRA cord1/crd4 : an early form of blindness.
  • PFK deficiency Exercise intolerance.
  • Fucosidosis Severe neurodegenerative disease (rare).
  • Blackbird gene : only if blackbird dress.
  • L-2-HGA hereditary neurological disease (motor disorders, seizures).
  • PRA cord1/crd4 : very frequent → early blindness.
  • Blackbird gene : useful according to dress.
  • Blackbird gene (Cardigan): important in reproduction.
  • X-SCID (Pembroke): severe immune deficiency (rare but serious).
  • PRA A hereditary form that can appear late in life.

Cat breeds

  • PRA rdAc progressive degeneration of the retina (night blindness followed by day blindness).
  • Pyruvate kinase deficiency chronic hereditary anaemia.
  • PRA rdAc : a frequent form in certain bloodlines.
  • Pyruvate kinase deficiency chronic haemolytic anaemia.
  • Polycystic kidney disease (PKD) Development of cysts in the kidneys leading to progressive renal failure. Very common in these lines.
  • Gangliosidosis GM2 severe neurodegenerative disease caused by a toxic accumulation in neurons.
  • Hypertrophic cardiomyopathy (HCM A31P) thickening of the heart muscle which can lead to heart failure and the risk of thrombosis.
  • Pyruvate kinase deficiency chronic haemolytic anaemia.
  • Polycystic kidney disease (PKD) Development of cysts in the kidneys leading to progressive renal failure. Very common in these lines.
  • Glycogenosis type IV severe metabolic disease, leading to weakness and early death.
  • Pyruvate kinase deficiency chronic anaemia.
  • PKD very frequent; formation of renal cysts → progressive renal failure.
  • HCM R820W A hereditary form of hypertrophic cardiomyopathy, which can lead to heart failure or sudden death.
  • PKD Present but less frequent.
  • Gangliosidosis GM1 severe neurodegenerative disease (motor loss, blindness, early death).
