We have just found out my 17 year old daughter has tested positive for the HLA B27 gene. She has been experiencing back pain for a while now, that has been getting worse and our GP ran various bloods. Does anyone know much about this gene and the conditions linked to it? We unfortunately were told via text message by the GP and she has been referred to Rheumatology but we are still waiting for her appointment to come through, so no opportunity to discuss with a professional as yet. I have had a look on the internet but ended up down a rabbit hole and genuinely terrified for her. I understand that a positive test doesn't necessarily mean that she will have any of the conditions associated, but my worry is that she is symptomatic, therefore it is more likely.
