Klinefelter'S Syndrome in a Western Lowland Gorilla (Gorilla gorilla gorilla) and Its Management.

Klinefelter's syndrome is the most prevalent sex chromosomal disorder in humans and has been observed in various mammalian species. This article documents the case of a 25-year-old western lowland gorilla (Gorilla gorilla gorilla) at Longleat Safari Park who was diagnosed with Klinefelter's syndrome. The study encompasses their diagnosis, behavioral assessment, and management strategies over twelve years. The behavioral profile includes neophobia, sensitivity to sounds, impaired problem-solving abilities, mood swings, and atypical social interactions. Management practices tailored to his condition involved establishing a consistent daily routine, mitigating exposure to sudden noises, and pre-emptive medical interventions at early signs of illness. These approaches have effectively addressed his unique needs and reduced stress-related behaviours. This case study underscores the necessity for individualized care plans for nonhuman primates with Klinefelter's syndrome, providing a guide for future management of similar cases in captivity. The findings contribute to the limited knowledge of Klinefelter's syndrome in gorillas and highlight the importance of personalized and consistent management strategies to enhance the welfare of affected individuals.
