with great interest I read your message about Bruck syndrome.
Although I did not work on Bruck syndrome up to now and I cannot do any biochemical analysis to confirm the diagnosis I wanted to discuss a possible molecular genetic approach.

In fact, I am a Human Geneticist interested in bone phenotypes from a scientific point of view, and maybe I could offer some kind of molecular diagnostics. Although Bruck syndrome is caused by a biochemical defect in telopeptide lysyl hydroxylase (PNAS 1999;96:1054-8), the underlying genetic defect is not known. Yet, the authors of the above mentioned paper did find a positive linkage on chromosome 17. This means that also in your family a linkage analysis may be possible if the family is of sufficient size.

In case you might be interested in this possibility I would be happy to hearing from you to discuss this point in more detail.

Best regards

Few days ago, I came across a case of familial repeated fractures and webbing that looks almost exactly as the published cases with Bruck syndrome. The defect is in bone-specific telopeptide lysyl hydroxylase on chromosome 17. However, I could not find a Lab that carries routine investigation of this enzyme. Please, let me know if it is possible to collaborate with any facility to confirm the diagnosis and/or plan for future prenatal diagnosis (Parents are planning to have more children)
