Menkes disease: a rare cause of bilateral inguinal hernias

Area of Science:

• Genetics
• Pediatrics
• Neuroscience

Background:

• Menkes disease is a rare X-linked recessive disorder caused by mutations in the copper-transporting ATPase 8A1 (ATP7A) gene.
• It is characterized by copper deficiency due to impaired intestinal absorption and distribution, leading to a spectrum of clinical manifestations.
• The classical presentation includes characteristic kinky hair, failure to thrive, and severe neurological impairment.

Observation:

• This report details a 4-month-old infant diagnosed with Menkes disease.
• The patient presented with bilateral inguinal hernias, an uncommon initial manifestation.
• This observation suggests a broader clinical spectrum for Menkes disease than typically recognized.

Findings:

• Radiographic and clinical evaluations confirmed the classical skeletal abnormalities associated with Menkes disease.
• Neurological assessments revealed the expected severe neurodegenerative changes characteristic of the disorder.
• The co-occurrence of inguinal hernias was noted as a significant, though unusual, clinical feature.

Implications:

• The findings underscore the need for heightened clinical suspicion for Menkes disease in infants presenting with seemingly unrelated congenital anomalies like inguinal hernias.
• Early recognition and diagnosis are crucial for timely intervention and management, potentially improving outcomes for affected children.
• This case contributes to the understanding of the variable phenotypic expression of Menkes disease, emphasizing the importance of comprehensive evaluation.
