Genetics of vascular anomalies

Area of Science:

• Vascular biology and genetics
• Developmental disorders
• Genomic medicine

Background:

• Vascular anomalies are diverse developmental defects of blood vessels.
• While some forms are inherited, most vascular anomalies occur sporadically.
• Somatic mosaicism, where cells have different genetic mutations, is increasingly recognized as a key factor in their formation.

Purpose of the Study:

• To explore the genetic underpinnings of vascular anomalies.
• To understand the role of specific genes and proteins in vascular development.
• To identify potential therapeutic targets and treatment strategies.

Main Methods:

• Utilizing Next-Generation Sequencing (NGS) for high-throughput screening of DNA and RNA from blood and lesional samples.
• Employing advanced genetic analysis to detect low-frequency somatic mutations.
• Developing in vitro and in vivo models based on identified genetic mutations.

Main Results:

• Significant increase in the identification of novel causative mutations for various vascular anomalies over the past decade.
• Elucidation of pathogenic mechanisms underlying vascular malformations.
• Detection of shared mutations and signaling pathways with cancers.

Conclusions:

• Somatic mosaicism is a critical mechanism in the pathogenesis of vascular anomalies.
• Genetic discoveries are crucial for understanding disease mechanisms and developing targeted treatments.
• Repurposing existing cancer therapies may offer effective treatment options for vascular anomalies.
