Laurence-Moon-Bardet-Biedl syndrome

Area of Science:

• Genetics
• Hepatology
• Rare Diseases

Background:

• Laurence-Moon-Bardet-Biedl syndrome (LMBBS) is an autosomal recessive disorder characterized by genetic heterogeneity and variable expressivity.
• LMBBS typically presents with a constellation of symptoms including obesity, retinal degeneration, polydactyly, and intellectual disability.
• Nonalcoholic steatohepatitis (NASH) is a chronic liver disease associated with metabolic dysfunction.

Observation:

• A case of LMBBS with a typical phenotype is presented.
• The patient also exhibited nonalcoholic steatohepatitis, a condition not commonly associated with LMBBS.
• The diagnosis of LMBBS was delayed until the patient sought hospital care.

Findings:

• This report details a rare co-occurrence of Laurence-Moon-Bardet-Biedl syndrome and nonalcoholic steatohepatitis.
• The typical phenotype of LMBBS was observed alongside the liver condition.
• Diagnostic delay underscores the challenge posed by the variable expression of LMBBS.

Implications:

• Recognizing the association between LMBBS and NASH may improve diagnostic accuracy for patients presenting with overlapping symptoms.
• Understanding the phenotypic variability of LMBBS is crucial for early identification and management.
• Further research may elucidate shared genetic or environmental factors contributing to this co-occurrence.
