Congenital muscular dystrophy in a dog with a LAMA2 gene deletion.


ABSTRACT: A 2-year-old female spayed dog was presented with a chronic history of short-strided gait and inability to completely open the jaw. Clinical signs were present since the dog was adopted from a humane society at a few months of age. Serum creatine kinase activity was abnormally high. Neurological examination, electromyography, muscle biopsies with immunofluorescent staining, and whole genome sequencing (WGS) were performed. A dystrophic phenotype was identified histologically in muscle biopsies, deficiency of laminin α2 protein was confirmed by immunofluorescent staining, and a deletion in the LAMA2 gene was identified by analysis of the WGS data. Congenital muscular dystrophy associated with a disease variant in LAMA2 was identified.
