We will be praying for you. It is possible to come down with the spondy diseases at the age of 10. Also HLA -B27 is only an indicator. Approximately 10 to 20 percent of those who suffer from the spondy diseases are negative. How is this possible.
Genes work in concert with other genes.
The most likely gene to be involved is HLA-B27, but a whole bunch of genes are involved in operating your immune system. Therefore it must be possible to have the spondy diseases without B27. Saying only one gene causes something is making what really happens too simple.
