In order for a geneticist to diagnose a patient with Marfan Syndrome, Ehlers-Danlos or Mixed and Undifferentiated Connective Tissue Disease, there needs to be a complete consult and a very involved medical history (with questions about familial traits and hereditary disorders) completed.
At least 2 of the 6 body systems most effected by the genetic traits should bear signs of connective tissue disease:
Occular - high internal vitreous pressures as a predictor of glaucoma or dislocation of the occular tendons...
Skeletal - EDS makes provisions for short, stocky individuals and Marfans for a tall, lean body with long digits and concave or peaked sternum as well, combined with the Central Nervous System, the dural tissue could be effected and exhibited by sciatica, chronic lower back pain, scoliosis can be present, etc. Joints can be highly flexible, the palate can be very high with crowded teeth and patients often have flat feet.
We know Cardio problems such as valvular prolapse and stenosis and aneurysms, plus the vessels in the abdomen can be very tangled (as are mine) giving rise to kidney disease and clotting problems.
and Marfans sufferers also have increased risks of pneumothorax.
UCT Disease patients will be diagnosed if there are related signs such as those above and hyper-elastic skin, psoriasis, detached retina, astigmatism or myopia and the list goes on.
I think that if you have dislocates, wear glasses and have valve disease a consult with a geneticist should be considered and not dismissed out of hand. My PCP asked me what I hoped to learn in such a consult, I have children and would have thought that the answer to that was evident. To end the conversation he said he wouldn't feel comfortable writing the order for a consult and I've got multiple connective tissue problems. I'm going to approach my Internist with the cardiology fellowship about initiating the order. If it weren't such a difficult process, where I live, to replace my PCP I'd seriously consider doing so.
