Weissenbacher–Zweymuller syndrome (WZS), also called Pierre-Robin syndrome with fetal chondrodysplasia,[1] is an autosomal recessive[2] congenital disorder, linked to mutations (955 gly -> glu) in the COL11A2 gene (located on chromosomal position 6p21.3), which codes for the α2 strand of collagen type XI.[1][2] It is a collagenopathy, types II and XI disorder.


It causes facial abnormalities, skeletal malformation and occasionally neural tube defects; the skeletal disfigurements resolve to a degree in the course of development.

Mutations in different parts of the gene may lead to deafness or Stickler syndrome type III (eye problems: myopia, retinal detachment and skeletal abnormalities).


It was first characterized in 1964 by G. Weissenbacher and Ernst Zweymüller.[3][4]
