What are the genetic changes related to Weissenbacher-Zweymller syndrome ?
Mutations in the COL11A2 gene cause Weissenbacher-Zweymller syndrome. The COL11A2 gene is one of several genes that provide instructions for the production of type XI collagen. This type of collagen is important for the normal development of bones and other connective tissues that form the body's supportive framework. At least one mutation in the COL11A2 gene is known to cause Weissenbacher-Zweymller syndrome. This mutation disrupts the assembly of type XI collagen molecules, resulting in delayed bone development and the other features of this disorder.
