What is Ehlers-Danlos syndrome

Ehlers-Danlos syndrome (EDS) is a group of inherited disorders that affect your connective tissues, mainly your skin, joints and blood vessel walls.

Those with this genetic disorder typically do not live beyond their 40s, doctors told TNP. Francis suffers from EDS Type 4, also known as vascular EDS, in which blood vessels in one's body is formed with defective collagen. The defective collagen, which is very fragile, can cause the walls of your blood vessels, intestines or uterus to rupture.

This results in easy bruising, said Dr Chia Kok Hoong of Dr Chia KH Vein Vascular & General Surgery Centre.

Those born with this genetic disorder are usually skinny and small in build, and have very pale translucent skin.

While he was unable to provide statistics, Dr Chia said he has only seen three patients with this genetic disorder in 28 years of experience.

According to the US National Library of Medicine, EDS Type 4 is very rare and is estimated to affect about 1 in 250,000 people globally.
