Degenerative Myelopathy (DM) DNA TestDMSOD1

Degenerative Myelopathy (DM) is a progressive disease of the spinal cord that usually appears in older dogs. It gradually weakens the hind limbs, leading to loss of coordination and eventually difficulty walking. It is not painful, but it is progressive. Knowing a dog's status supports breeding decisions and early awareness.
An autosomal recessive condition with variable expression between breeds caused by a mutation in the SOD1 gene.
Inheritance: autosomal recessive

Hyperuricosuria (HUU) DNA TestHUUSLC2A9

Hyperuricosuria (HUU) is caused by a variant in the SLC2A9 gene, which affects how the body processes and removes uric acid. Affected dogs are at increased risk of developing urinary stones, which can cause signs such as blood in the urine, frequent or difficult urination, and in severe cases, urinary blockage. HUU is inherited as an autosomal recessive condition, meaning a dog must inherit two copies of the variant to be genetically affected.

Degenerative MyelopathyDM

Degenerative Myelopathy (DM) is a progressive disease of the spinal cord that usually appears in older dogs. It gradually weakens the hind limbs, leading to loss of coordination and eventually difficulty walking. It is not painful, but it is progressive. Knowing a dog's status supports breeding decisions and early awareness.
An autosomal recessive condition with variable expression between breeds caused by a mutation in the SOD1 gene.

Signs to look for

Usually from around 8 years old: wobbliness or dragging of the hind paws, loss of coordination in the back legs, worn nails, and gradually progressing hind-limb weakness.

How it's inherited

Recessive with incomplete penetrance — a dog needs two copies to be at risk, but not every at-risk dog develops signs.

What your result means

Clear (N/N): no copies of the variant; not expected to develop this inherited form.

Carrier (N/DM): one copy. Very unlikely to develop DM, but can pass the variant on.

At risk (DM/DM): two copies. At risk of developing DM, though not all at-risk dogs do.

HyperuricosuriaHUU

Hyperuricosuria (HUU) is caused by a variant in the SLC2A9 gene, which affects how the body processes and removes uric acid. Affected dogs are at increased risk of developing urinary stones, which can cause signs such as blood in the urine, frequent or difficult urination, and in severe cases, urinary blockage. HUU is inherited as an autosomal recessive condition, meaning a dog must inherit two copies of the variant to be genetically affected.

How it's inherited

Recessive

What your result means

Clear (N/N): no copies; not expected to develop HUU, nor pass it on.

Carrier (N/HUU): one copy. Healthy, but can pass it on. Breeding two carriers risks affected puppies.

Affected (HUU/HUU): two copies; expected to develop HUU. Discuss with your vet.

Degenerative MyelopathyDM

Gene: SOD1
Variant: c.118G>A (p.Glu40Lys)
Inheritance: autosomal recessive
OMIA: OMIA 000263 9615
Reported frequency: One of the most widespread canine disease variants, reported across very many breeds with varying penetrance.

Molecular mechanism

Degenerative Myelopathy (DM) is a progressive neurodegenerative disease of the spinal cord that typically affects dogs older than 8 years of age. The condition is characterised by progressive muscle atrophy and weakness of the limbs, advancing to tetraparesis (Awano et al., 2009) and eventually respiratory muscle failure (Nardone et al., 2016). DM is inherited as an autosomal recessive condition with variable expression between breeds. Missense mutation (c.118G\u0026gt;A; p.E40K) in exon 2 of the SOD1 gene on canine chromosome 31 (CFA31) was identified as the primary genetic risk factor by Awano et al., (2009). However, some dogs homozygous for the variant remain clinically unaffected, demonstrating incomplete penetrance. The SOD1.118G\u0026gt;A risk allele has been identified in 222 dog breeds. Burnese Mountain Dogs are also susceptible to this version of DM in addition to their breed-specific variant of DM, see DM- BMD variant for further information.

HyperuricosuriaHUU

Gene: SLC2A9
Variant: c.616G>T; p.Cys188Phe
Inheritance: autosomal recessive
OMIA: OMIA000256 9615

Molecular mechanism

Hyperuricosuria (HUU)or Urolithiasis is an inherited metabolic disorder characterised by impaired uric acid transport, resulting in increased urinary excretion and blood concentrations of uric acid. Affected dogs are predisposed to the formation of ammonium urate uroliths within the urinary tract, although not all dogs carrying the causative variant will develop the disease (Bannasch et al., 2008). Clinical signs are associated with stone formation and may include haematuria, pollakiuria, dysuria and urethral obstruction, while severe obstruction can result in systemic illness including anorexia, vomiting, collapse and metabolic disturbances (Bartges et al., 1999; Bartges and Callens, 2015).
Hyperuricosuria is inherited as an autosomal recessive condition; however, the SLC2A9 variant represents a genetic risk factor for urate urolithiasis rather than a definitive predictor of clinical disease. Bannasch et al., (2008) identified a missense mutation (c.616G\u0026gt;T; p.Cys188Phe) in the SLC2A9 gene on canine chromosome 3 (CFA3) as the causative variant. The variant is fixed in Dalmatians, with all dogs reported to be homozygous, but has also been identified at lower frequencies in several other breeds, including Labrador Retrievers, Bulldogs, German Shepherd Dogs and Pomeranians (Bannasch et al., 2008; Karmi et al., 2010; Cosgrove et al., 2015).
