Bart syndrome, also known as aplasia cutis congenita type VI, is a rare genetic disorder characterized by the association of congenital localized absence of skin, mucocutaneous blistering and absent and dystrophic nails.[1][2]
History
This clinical trial was first described by Bruce J Bart in 1966, who reported a large family with 26 affected members.
Clinical
1. Absence of skin at birth, involving the lower legs and feet, healing within a few months, leaving scarring and fragile skin. 2. Widespread blistering of the skin and mucous membranes. 3. Variable absence and dystrophy of nails.
Genetics
The syndrome is inherited by
autosomal dominant transmission with complete penetrance but variable expression. This means that children of an affected parent that carries the gene have a 50% chance of developing the disorder, although the extent to which they are affected is variable.[citation needed

Blistering in Bart syndrome represents a form of epidermolysis bullosa caused by
COL7A1).[3]
