Heterozygous glycine substitution in the COL11A2 gene in the original patient with the Weissenbacher-Zweymüller syndrome demonstrates its identity with heterozygous OSMED (nonocular Stickler syndrome)

Am J Med Genet. 1998 Nov 2;80(2):115-20. doi: 10.1002/(sici)1096-8628(19981102)80:2<115::aid-ajmg5>3.0.co;2-o.


The original patient with the Weissenbacher-Zweymüller syndrome was analyzed for mutations in two candidate genes expressed in cartilage (COL2A1 and COL11A2). No mutations were found in the COL2A1 gene but the COL11A2 gene contained a single-base mutation that converted a codon for an obligate glycine to a codon for glutamate at position alpha 2-955 (G955E). The results here and those published previously indicate that the Weissenbacher-Zweymüller syndrome (heterozygous OSMED), nonocular Stickler syndrome, and homozygous OSMED are all caused by mutations in the COL11A2 gene.
