Weissenbacher-Zweymüller syndrome
Overview
Overview
Weissenbacher-Zweymuller syndrome is an autosomal recessive genetic 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.
Presentation
Presentation
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).
