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

Degenerative Myelopathy - Bernese Mountain Dog (DM-BMD) DNA TestDM-BMDSOD1

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.
Please note that although this variant is specific to BMD only, the all breeds variant of DM may also affect BMD.

Von Willebrand Disease Type 1 (VWD1) DNA TestVWD1VWF

Von Willebrand Disease (VWD) is a bleeding disorder which affects blood clotting. Affected dogs may have nosebleeds and bruise easily, as well as bleed heavily after injury or surgery. Most dogs will have a normal life expectancy but this condition should be noted to veterinarians in the case of surgery.
An autosomal recessive condition caused by a mutation in the VWF gene.

Please note: This test is for Von Willebrand Disease Type 1 only. Please check which type of VWD affects your breed before ordering this as a single test. If this test is included in a breed health package, it is relevant to that breed.

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.

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.

Von Willebrand Disease Type 1VWD1

Gene: VWF
Variant: VWF c.7437G>A
Inheritance: autosomal recessive
OMIA: OMIA001339 9615

Molecular mechanism

Von Willebrand Disease (vWD) is an inherited bleeding disorder caused by deficiency or dysfunction of von Willebrand factor (vWF), a plasma glycoprotein essential for normal platelet adhesion and blood clotting (Boudreaux, 2012). Affected dogs may experience prolonged bleeding following injury or surgery, spontaneous bleeding from the nose or gums, bruising, or blood in the urine (Thomas, 1996). Three recognised forms of the disease exist, which differ in severity: Type I is characterised by reduced concentrations of normal vWF and typically causes mild to moderate bleeding, Type II results from qualitative defects in the vWF protein and is associated with moderate to severe bleeding, while Type III is characterised by an almost complete absence of vWF and is the most severe form of the disease.
The genetics and inheritance of von Willebrand Disease vary according to the disease type and breed. Type I is associated with the VWF c.7437G\u0026gt;A splice-site variant and shows autosomal dominant inheritance with incomplete penetrance in some breeds, including Doberman Pinschers and Kromfohrländers, while autosomal recessive inheritance has been proposed in others (Gentilini and Turba, 2013; Segert et al., 2019). As a result, the Type I genetic test identifies dogs carrying the risk variant but should be interpreted alongside clinical findings and additional haemostatic testing where appropriate (Segert et al., 2019).

Please note: This test is for Von Willebrand Disease Type 1 only. Please check which type of VWD affects your breed before ordering this as a single test. If this test is included in a breed health package, it is relevant to that breed.
