Neuroaxonal Dystrophy (Discovered in the Rottweiler; VPS11-related)
Neuroaxonal Dystrophy (Discovered in the Rottweiler; VPS11-related). Autosomal recessive. Observed in 7 of 266 breeds tested in the Sniff Atlas, with measured carrier frequencies drawn from 242,665 dogs (Donner 2023). Per-dog phenotype outcome depends on penetrance, modifiers, and environment; the carrier frequencies below describe variant prevalence, not disease incidence.

A model of human hypomyelinating leukodystrophy 12
This is the canine counterpart of hypomyelinating leukodystrophy 12 in people. That makes affected dogs a naturally-occurring model of the human disease, and it is part of why studying dogs moves medicine forward for everyone. It does not mean your dog has the human disease. It means the two share an underlying biology.
In people, the disease is described as: Any leukodystrophy in which the cause of the disease is a mutation in the VPS11 gene.
In humans it is also called: HLD12, hypomyelinating leukodystrophy type 12, leukodystrophy caused by mutation in VPS11, leukodystrophy, hypomyelinating, 12, leukodystrophy, hypomyelinating, type 12.
Mapped from OMIA via the human disease's OMIM entry to the Mondo Disease Ontology (Monarch Initiative, CC-BY 4.0). Sniff renders this as a model-of link; the canine disease remains the subject of this page.
From OMIA's curated record
Documented in OMIA (Online Mendelian Inheritance in Animals). This describes the disease as recorded in the published literature, not a prediction for any individual dog. As of 2026-06-03.

Set each parent's status for Neuroaxonal Dystrophy (Discovered in the Rottweiler; VPS11-related) and see the odds for their puppies. Single recessive variant, exact Mendelian math.
These are the genetic odds for one known variant, not a promise: a real litter varies around them, and penetrance or other genes can change whether the condition ever appears. Use it to avoid pairing two carriers and to keep a line healthy, not to engineer a dog. Inheritance mode per OMIA.

The list below is split into well-sampled breeds (n ≥ 50 tested) and small-sample breeds (n < 50, where the Wilson CI typically spans more than 20 percentage points and frequencies should not be compared directly to the well-sampled entries). Frequencies are population-level, not per-litter or per-line.

From genotype to phenotype
Carrier status is not the same as disease status. Penetrance is the fraction of at-risk dogs that develop the phenotype. The Donner 2023 S4 table tracks this for 1 variant(s) underlying this disease in the cohort.
- At-risk dogs evaluated
- 2
- Phenotype confirmed
- 2
- Penetrance range
- not yet quantifiable
Fewer than 20 at-risk dogs evaluated; too few to state a penetrance figure.
Predicted disease relevance at the per-dog level is UNPROVEN. The carrier frequency is measured; phenotype outcome is governed by penetrance, environment, and modifier loci. Consult a veterinarian for clinical interpretation.
