Larsen's syndrome: clinical and genetic aspects

Area of Science:

• Genetics
• Orthopedics
• Ophthalmology

Background:

• Larsen syndrome is a rare congenital disorder characterized by skeletal abnormalities.
• Genetic heterogeneity is observed in Larsen syndrome, with both dominant and recessive inheritance patterns reported.
• Understanding the genetic basis is crucial for diagnosis and management.

Observation:

• A family presented with a case of Larsen syndrome in a young girl.
• Clinical manifestations included joint dislocations, distinctive facial features, and bone abnormalities.
• Divergent strabismus was noted as an additional clinical finding.

Findings:

• The described case of Larsen syndrome exhibited a genetic recessive origin.
• The study highlights the variability in Larsen syndrome presentation and inheritance.
• Differential diagnosis considerations for Larsen syndrome are discussed.

Implications:

• This case underscores the importance of recognizing the diverse clinical spectrum of Larsen syndrome.
• Accurate genetic diagnosis aids in family counseling and prognosis.
• Identifying associated conditions like strabismus improves comprehensive patient care.
