To date, only two feline causal variants have been identified. This study reports two cases of male Maine coon siblings that presented with muscular hypertrophy, growth retardation, weight loss, and vomiting. (2) Both cats were clinically examined and histopathology and immunofluorescent staining of the affected muscle was performed. DMD mRNA was sequenced to identify putative causal variants. (3) Both cats showed a significant increase in serum creatine kinase activity. Electromyography and histopathological examination of the muscle samples revealed abnormalities consistent with a dystrophic phenotype. Immunohistochemical testing revealed the absence of dystrophin, confirming the diagnosis of dystrophin-deficient muscular dystrophy. mRNA sequencing revealed a nonsense variant in exon 11 of the feline DMD gene, NC_058386.1 (XM_045050794.1): c.1180C &gt; T (p.(Arg394*)), which results in the loss of the majority of the dystrophin protein. Perfect X-linked segregation of the variant was established in the pedigree. (4) ddMD was described for the first time in the Maine coon and the c.1180C&gt;T variant was confirmed as the causal variant.<\/jats:p>","DOI":"10.3390\/ani12212928","type":"journal-article","created":{"date-parts":[[2022,10,25]],"date-time":"2022-10-25T12:29:45Z","timestamp":1666700985000},"page":"2928","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["A Nonsense Variant in the DMD Gene Causes X-Linked Muscular Dystrophy in the Maine Coon Cat"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0583-8705","authenticated-orcid":false,"given":"Evy","family":"Beckers","sequence":"first","affiliation":[{"name":"Department of Veterinary and Biosciences, Faculty of Veterinary Medicine, Ghent University, B-9820 Merelbeke, Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ine","family":"Cornelis","sequence":"additional","affiliation":[{"name":"Small Animal Department, Faculty of Veterinary Medicine, Ghent University, B-9820 Merelbeke, Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3590-8348","authenticated-orcid":false,"given":"Sofie F.
