My name is Jane. My family has been effected by a condition know as Chiari Malformation. Basically it is where part of cerebellum protrudes down into your spinal canal. It causes many different symptoms. When I was first diagnosed in 1994 I believed I was the only one with this disease in my family. Since then 8 family members have been diagnosed. Presently we are in a study with Duke University for the genetic link. Since my cousin on my maternal side has two of the diagnosis we are convinced that the connection is maternal. We are just not sure what line it came from my Grandmother Hill mainly from Atlantic County, NJ or Grandfather Larrisey from Phila,Pa. Anyone from either of those family lines with info please contact me. Thanks!
