Cross-species summary: This disorder is a lysosomal storage disease, caused by a deficiency of the lysosomal enzyme N-acetylgalactosamine 4-sulfatase.

Molecular basis: By cloning and sequencing a very likely comparative candidate gene (based on the homologous disorder in other species), Berman et al. (2004) were the first to report a molecular basis of this disorder, as follows: "When the DNA coding sequence from miniature pinschers affected with MPS VI was compared to the normal canine sequence, a single missense mutation (G to A) was identified. This mutation, occurring in exon V, replaces the tiny amino acid glycine with a bulky arginine in a highly conserved region of the protein and is found only in affected dogs."

Jolly et al. (2012) reported a different mutation in a Miniature Poodle-type of dog: "A novel homozygous 22 base pair (bp) deletion in exon 1 of this enzyme's [ARSB] gene was identified (c.103_124del), which caused a frameshift and subsequent premature stop codon."

Pérez et al. (2015) reported an affected Miniature Schnauzer homozygous for the same variant as reported by Berman et al. (2004).

Wang et al. (2017) reported an affected Great Dane homozygous for a "nonsense mutation (c.295C>T) in exon 1, replacing glutamine with a premature stop codon (p.Gln99*), predicting no enzyme synthesis".

Breeds: Chesapeake Bay Retriever, Great Dane, Miniature Pinscher, Miniature Poodle, Miniature Schnauzer, Toy Poodle, Welsh Corgi.

By default, variants are sorted chronologically by year of publication, to provide a historical perspective. Readers can re-sort on any column by clicking on the column header. Click it again to sort in a descending order. To create a multiple-field sort, hold down Shift while clicking on the second, third etc relevant column headers.

WARNING! Inclusion of a variant in this table does not automatically mean that it should be used for DNA testing. Anyone contemplating the use of any of these variants for DNA testing should examine critically the relevant evidence (especially in breeds other than the breed in which the variant was first described). If it is decided to proceed, the location and orientation of the variant sequence should be checked very carefully.
