  • To stimulate new ideas 
  • To encourage new researchers to enter the field, to collaborate with others in the field and to collaborate with our patient organizations
  • To identify the gaps and unmet needs for our heterogenous patient populations

The conditions covered in this meeting include:

  • CLAPO Syndrome
  • CLOVES Syndrome
  • DCMO
  • Facial Infiltrating Lipomatosis (FIL)
  • Fibroadipose Vascular Anomaly (FAVA)

Abstract Submission:

The Conference Organizing Committee invites authors to submit abstracts to be considered for inclusion in the Scientific Program for either oral or poster presentations.  We encourage submissions that cover the entire spectrum of PIK3CA Related Conditions including:  CLOVES, Macrodactyly, CLAPO, DCMO, KTS, FAVA, M-CM, HHML, Isolated Lymphatic and Venous Malformations, GLA and FIL.  

The conference sessions will be organized around the themes of Basic Science, Preclinical Research, Diagnosis/Natural History and Treatment, however other topics of research are encouraged and welcomed for submission. Within each of these themes we will bring together basic scientists and clinicians, in the hope of stimulating and educating both. 

Abstract submissions open May 1, 2021 and are due June 22, 2021 at 11:59pm EST.   All submitters will receive notification of abstract acceptance and presentation type by August 2, 2021.

  • Dr. Miikka Vikkula
  • Professor of Human Genetics
  • Co-Director of de Duve Institute

More about Dr. Miikka Vikkula

Professor Vikkula obtained his M.D. at the University of Helsinki in 1992 and his Ph.D. in molecular genetics, in 1993. He was a Research Associate at Harvard Medical School 1993- 1997, during which time he became interested in vascular and lymphatic anomalies. With his wife, Professor Laurence Boon, Plastic Surgeon, Co-ordinator of the Vascular Anomaly Center, Brussels, the couple discovered the gene for familial venous malformation in 1996, and since then many others. They settled in Brussels in 1997, where Dr. Vikkula developed his own laboratory. He obtained a “docentship PhD”; in 2000, and was nominated Assistant Professor at the Faculty of Medicine in UCL. He is a member of the Directorate of the de Duve Institute since 2004, and a full professor of Human Genetics since 2013. He has received numerous honors and awards, including the Inbev-Baillet Latour Clinical Prize in 2013, and the first Belgian Generet Award for rare disease research in 2019. He is a Member of the Royal Belgian Academy of Medicine since 2012. Professor Vikkula’s research led to the identification of first somatic mutations as explanation for sporadically occurring vascular anomalies, generation of first ever animal models for vascular malformations, and proof of concept treatment with small molecular inhibitors. Clinical trials are now being conducted with various molecules in various countries. Professor Vikkula is well-known internationally as a major contributor to the understanding of molecular basis of vascular anomalies and lymphedema with more than 160 peer-reviewed publications and more than 50 reviews and chapters in major biomedical textbooks.
