Understanding Lab Tests for Beckwith-Wiedemann Syndrome
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Beckwith-Wiedemann syndrome (BWS) is a rare congenital overgrowth disorder typically diagnosed through clinical features and genetic testing. While there isn't a single blood test to diagnose BWS itself, laboratory monitoring plays an important role in assessing growth-related factors and monitoring for potential complications.
Recommended Test
IGF-2
This test measures insulin-like growth factor-2 levels in the blood. Beckwith-Wiedemann syndrome is associated with overexpression of the IGF-2 gene, leading to elevated IGF-2 levels that contribute to excessive growth and increased tumor development risk. Monitoring these levels helps healthcare providers assess the biochemical activity related to the syndrome.

The Role of Blood Testing in BWS Management
BWS is characterized by overgrowth, increased risk of embryonal tumors, and various metabolic abnormalities. Blood tests are fundamental for monitoring the biochemical changes associated with this condition, particularly growth factors that may contribute to excessive growth and tumor development risk.
Understanding IGF-2 in BWS
IGF-2 is a key growth factor that, when overproduced, can drive the characteristic overgrowth seen in BWS. Regular monitoring of IGF-2 levels provides valuable information about the underlying molecular activity and may help guide clinical management decisions.
Important Considerations
The information here is for educational purposes only and is not a substitute for professional medical advice. Always consult with a healthcare provider for diagnosis and treatment. BWS management typically involves a multidisciplinary approach including genetic counseling, regular tumor surveillance, and monitoring of growth parameters.
