Oto-spondylo-megaepiphyseal dysplasia (OSMED): clinical and radiological findings in sibs homozygous for premature stop codon mutation in the COL11A2 gene.
We describe here the clinical findings of two Turkish cousins with OSMED carrying a novel homozygous truncating mutation in exon 38 of COL11A2 gene, c.2763delT, identified on cDNA and confirmed at gDNA.

HL due to mutations in COL11A2, encoding collagen type XI alpha-2, can be non-syndromic autosomal-dominant or autosomal-recessive, and also syndromic as in Otospondylomegaepiphyseal Dysplasia, Stickler syndrome type III, and Weissenbacher-Zweymuller syndrome.
