ARSB gene variants causing Mucopolysaccharidosis VI in Miniature Pinscher and Miniature Schnauzer dogs.

ABSTRACT: Mucopolysaccharidosis (MPS) VI is a lysosomal storage disease caused by a deficiency of N-acetylgalactosamine-4-sulfatase, also called arylsulfatase B (ARSB, EC 3.1.6.12). Dogs with MPS VI show progressive predominantly oculoskeletal signs homologous to those in human and feline patients. We report herein two pathogenic ARSB gene variants in Miniature Pinscher and Miniature Schnauzer dogs with MPS VI and a genotyping survey in these breeds. All exons and adjacent regions of the ARSB gene were sequenced from three affected Miniature Pinschers and three affected Miniature Schnauzers. Allelic discrimination assays were used for genotyping. A missense variant (NM_001048133.1:c.910G>A) was found in exon 5 of MPS VI-affected Miniature Pinschers that is predicted to result in a deleterious amino
