Histological examination of the thyroid gland revealed severe chronic diffuse bilateral atrophy with loss of thyroid follicles and lack of colloid. Pedigree analysis suggested an autosomal recessive transmission. Whole genome sequencing of an affected dog and filtering for private variants against 1539 control genomes identified a homozygous nonsense variant in the\n                    <jats:italic>TG<\/jats:italic>\n                    gene encoding thyroglobulin, NM_001048104.1:c.3694C&gt;T. The variant was predicted to introduce a premature stop codon truncating 55% of the wild\u2010type open reading frame, NP_001041569.1:p.(Arg1232*). The TG glycoprotein is the precursor to the thyroid hormones triiodothyronine (T3) and tetraiodothyronine (T4). TG deficiency leads to comparable phenotypes in human patients, cattle and goats. Genotyping six affected and 87 control Rottweiler dogs confirmed the expected genotype\u2013phenotype association, with all affected dogs being homozygous for the mutant allele and control dogs being either heterozygous or homozygous wild\u2010type. All four obligate carriers were heterozygous and among the 74 unrelated control dogs without known relationships to cases we found a 5.4% carrier frequency. Correct co\u2010segregation in the available families was also observed. Taken together, this study provides an initial clinical and pathological characterization of an inherited dwarfism syndrome in Rottweilers and identifies a\n                    <jats:italic>TG<\/jats:italic>\n                    variant as a causal genetic defect. The results enable genetic testing to avoid unintentional risk matings.\n                  <\/jats:p>","DOI":"10.1002\/age.70127","type":"journal-article","created":{"date-parts":[[2026,5,23]],"date-time":"2026-05-23T01:15:33Z","timestamp":1779498933000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["<scp>\n                      <i>TG<\/i>\n                    <\/scp>\n                    Nonsense Variant in Dwarf Rottweiler Dogs"],"prefix":"10.1002","volume":"57","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5615-7897","authenticated-orcid":false,"given":"Marie","family":"Abitbol","sequence":"first","affiliation":[{"name":"Univ Lyon, VetAgro Sup  Marcy\u2010l'Etoile France"},{"name":"Institut NeuroMyoG\u00e8ne INMG\u2010PGNM, CNRS UMR5261, INSERM U1315, Facult\u00e9 de M\u00e9decine, Rockefeller Universit\u00e9 Claude Bernard Lyon 1  Lyon France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michaela","family":"Dr\u00f6gem\u00fcller","sequence":"additional","affiliation":[{"name":"Institute of Genetics, Vetsuisse Faculty University of Bern  Bern Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0006-7595-2817","authenticated-orcid":false,"given":"Cleo","family":"Schwarz","sequence":"additional","affiliation":[{"name":"Institute of Genetics, Vetsuisse Faculty University of Bern  Bern Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Etienne","family":"Furthner","sequence":"additional","affiliation":[{"name":"Clinique Vetmidi Etoy &amp;
