RESUMO
O objetivo do trabalho foi identificar a presença no Brasil do gene mutante L2HGDH em cães da raça Staffordshire Bull Terrier (SBT). Para tanto foi feito o teste genético em 76 cães provenientes de diferentes regiões do Brasil, no período de 2008 a 2015, sendo encontrados 55 animais (72,37%) livres do gene mutante L2-HGDH ou homozigotos dominantes, e 21(27,63%) portadores do gene mutante ou heterozigotos. Não foi encontrado nenhum animal homozigoto recessivo (afetado), porém pode-se observar que o gene circula no Brasil e que cães afetados podem aparecer.(AU)
The aim of this study was to identify the presence of a mutation in the L2-hydroxyglutarate dehydrogenase (L2-HGDH) gene in Staffordshire bull terriers in Brazil. Genetic testing was done in 76 dogs from different regions of the country, from 2008 to 2015. Fifty-five dogs (72.37%) were free of the mutant gene L2HGDH or homozygous-dominant, and 21 (27.63%) were carriers for the mutant gene or heterozygous. No homozygous recessive dogs (affected) were found, however, it is worth noting that the gene circulates in Brazil and that affected dogs can appear.(AU)
