Genetic Test Available

Several years ago a dystrophin deficient muscular dystrophy was described in seven male Japanese Spitz dogs (Jones et al 2004) with clinical signs of slowly progressive exercise intolerance, generalized weakness and dysphagia (image of an affect Spitz below). Recently the causative mutation was identified for X-linked muscular dystrophy in this breed (Atencia et al 2013) and a genetic test is now available.
