OMIA 001309-9615 : Mucopolysaccharidosis IIIA in Canis lupus familiaris

See the equivalent entry at NCBI

Possible human homologue (MIM number): 252900

Mendelian trait/disorder: yes

Mode of inheritance: Autosomal Recessive

Considered a defect: yes

Key mutation known: yes

Year key mutation first reported: 2000

Cross-species summary: The only domestic species in which this lysosomal storage disease has been reported is dogs (Fischer et al., 1998).

Molecular basis: By cloning and sequencing a very likely comparative candidate gene (based on the homologous human disorder), Aronovich et al. (2000) reported a likely causal variant in Dachsunds as "a 3-bp deletion, 737-739delCCA, resulting in the loss of threonine at position 246 in both alleles of the propositus and in one allele of a healthy littermate".

Yogalingam et al. (2002) identified a single bp insertion (708-709insC) as a likely causative variant in New Zealand Huntaway dogs.

Breed: Wire-haired dachshund.
