Cutis laxa
A dermatologic condition characterized by unusually loose skin which may hang in pendulous folds.
Cutis laxa is usually a genetic disorder.
A mild autosomal dominant form can be caused by mutation in the elastin gene (the ELN gene).
Mutations in the gene encoding fibulin-5 (FBLN5) can cause either autosomal dominant or a more severe autosomal recessive form of cutis laxa.
There is also an X-linked type of cutis laxa
