I have KFS Klippel Feil Syndrome which is characterized by cervical vertabre fusions and other anomalies that are often associated. My C1 is fused to my skull, C2-C3, and C6 or C7 is fused to T1 or T 2, depending on who is reading the X-ray, LoL! I also have fusions lower down and a tethered cord, which they just found out at 58. I'm now having random loss of hand/arm control and hip/leg control. It is degenerative and sometimes (for now?), it is genetic but I don't carry any of the 3 known genes associated with KFS. Which means I have to hope I have impressed that my children should not risk continuing our lineage. I love my kids but I probably wouldn't have risked it, had I known. Grandkids were my biggest dream! Now, they are my greatest fear, but still dream?
