Leopard syndrome: a tropical rarity

Area of Science:

• Genetics and rare diseases
• Clinical case studies
• Dermatology and cardiology

Background:

• Leopard syndrome is a rare autosomal dominant disorder.
• Characterized by a constellation of clinical features affecting multiple organ systems.
• Genetic mutations in PTPN11, RAF1, or BRAF are commonly implicated.

Observation:

• A male patient from the Indian subcontinent presented with a classical phenotype of Leopard syndrome.
• Clinical manifestations included generalized lentiginosis, ocular hypertelorism, pulmonary stenosis, short stature, cryptorchidism, and pectus excavatum.
• The progressive nature of lentiginosis was a notable feature.

Findings:

• The patient displayed a typical constellation of symptoms consistent with Leopard syndrome.
• The combination of lentiginosis, cardiac defects (pulmonary stenosis), and dysmorphic features was prominent.
• This case underscores the importance of recognizing the syndrome's phenotypic variability.

Implications:

• Highlights the importance of early diagnosis and genetic counseling for Leopard syndrome.
• Contributes to the understanding of Leopard syndrome prevalence and presentation in diverse geographical regions.
• Emphasizes the need for multidisciplinary management involving genetics, cardiology, and dermatology specialists.
