Contact   External Profile



My name is Edith Friesema. Since 1994 I’m working in Erasmus MC, first as a PhD student, at the Department of Internal Medicine. Currently I’m an assistant Professor investigating genes involved in Cardiovascular Diseases and also the head of the laboratory of Porphyria Center Rotterdam. I use genetic approaches to find mutations in genes involved in rare metabolic diseases like Familial Hypercholesterolemia, Essential Hypertension and Porphyria. I combine basic research with diagnostics to investigate these metabolic diseases which will in the end result in a better understanding and treatment of our patients.

Field(s) of expertise

I use genetic approaches like Whole Exome Sequencing to search for novel disease-modifying genes but also Sanger Sequencing to find mutations in known candidate genes.

Education and career

In 1994 I started as PhD student in Endocrinology which resulted in 2001 in my thesis with title Thyroid Hormone Transporters. Thereafter I continued as Postdoc in Endocrinology. In this period I identified a specific thyroid hormone transporter (JBC 2003) which was linked to a phenotype of severe X-linked mental retardation (Lancet 2004). Since 2010 I’m an Assistant Professor in Vascular Medicine and since 2016 also head of the Laboratory of Porphyria Center Rotterdam.

Teaching activities

I‘m involved in teaching in the Bachelor of Medicine and Clinical Technology.


I'm currently using genetic approaches to identify novel disease-modifying genes related to Cardiovascular Diseases and also in different forms of Porphyria.
