Table 1 also contains the current list of all other known mutations resulting in other forms of canine MD. Thus, in addition to the many known forms of dystrophin-deficient MD across many breeds, the spectrum of known canine MDs also includes forms of limb–girdle MDs in the Boston terrier [22] and miniature dachshund [23], and congenital MDs associated with variants in COL6 in Landseer Newfoundland dogs [24], Labrador retrievers [25], and American Staffordshire terriers [26], in LAMA2 in the Italian greyhound [27] and Staffordshire bull terrier [28], and in LARGE1 in Labrador retrievers [29]. This evidence concerns the gene LAMA2 and myelodysplastic syndrome.
