Larsen Syndrome and Associated Spinal Deformities.

Area of Science:

• Genetics
• Orthopedics
• Developmental Biology

Background:

• Larsen syndrome is a rare connective tissue disorder.
• It impacts skeletal development and presents with joint dislocations and spinal anomalies.
• Mutations in the FLNB gene are the primary cause.

Purpose of the Study:

• To review the genetic basis of Larsen syndrome.
• To clarify its clinical manifestations and symptoms.
• To define current and potential therapeutic strategies.

Main Methods:

• A comprehensive literature search was conducted in the PubMed database.
• Inclusion criteria focused on molecular and clinical studies, management, surgical treatments, case reports, and reviews.
• Articles were selected based on full-text availability in English.

Main Results:

• Larsen syndrome results from mutations in the FLNB gene, affecting the filamin B protein essential for skeletal development.
• Key symptoms include congenital joint dislocations, distinctive facial features, and spinal deformities.
• Initial conservative treatment may be followed by surgical interventions like spinal fusion and decompression.

Conclusions:

• FLNB gene mutations underpin Larsen syndrome, manifesting in significant skeletal abnormalities.
• A combination of conservative and surgical approaches is typically required for management.
• Further research into novel therapeutic modalities is warranted for improved patient outcomes.
