Guest guest Posted January 27, 2003 Report Share Posted January 27, 2003 WELCOME Christy!! In Mitochondrial diseases there are two types of inheritance possible....Mitochondrial DNA or nuclear DNA. Some portion of both have been mapped and can be tested for, though there is also alot that they do not know yet, so you may or may not get some answers from this test. If its a mito DNA problem, 100% of the children are affected however when and how they present is very variable (this would also mean the mother and her mother and so on are affected also, again with a very wide presentation possible). If its a nuclear DNA problem, it follows a more traditional inheritance pattern (i.e. Autosomal Dominant, Autosomal Recessive, etc) and means there's a 25% chance of having another affected sibling, the affected siblings will generally present more similarly (but not always), and its more likely that one or both of the parents are carriers rather than affected. I've simplified this tremendously, but it gives you a basic idea. Looking forward to getting to know you and your family!! BIG hugs, Kass, proud mom to Chance(9), Madison(6) - both with confirmed mito, unknown defect, and Abby(5) - suspected McNair Family Website CaringBridge - mitowhat "momofmollyann " wrote: Hi Everyone, I just found out about this group from someone on the Infantile Spasms group. I was so glad to find out about this group. My daughter is Molly Ann and she just turned 2 in December. She was diagnosed at 5 months with having infantile spasms. Then at 9 months she was diagnosed with CP and Microcephaly. They gave her ACTH for the IS and she was spasm free for one year. The spasms returned in April of last year. She had some blood test and that is when they found out she had too much lactic acid in her blood. Our Doctor( Ritter-Minnesota Epilepsy Group) suggested we should go to Atlanta, GA to see Doctor Schoffner to have a muscle biopsy and spinal tap. He thought she might have a mito disorder. Six months later we found out she did. They said her most prominent defect is with involves the flow of electrons through Complex I with some slight decrease in IV. They also said that they would do DNA sequencing to differentiate between Nuclear mutation and a mitochondrial mutation once they see if our insurance will okay it. Can someone tell me what this means? I am still confused about alot of this. I am just so happy that she is alive and growing after all she has been through. She is very delayed in all areas. She can't sit, walk or talk. She does'nt feed herself, but she can eat regularly, so for that we are greatful. When they found out about her mito disorder(no name) they changed her supplements and added a bunch of things. She takes: B6 B Complex Carnitor CoQ10 with Vitamin E Selenium Biotin MCT Oil Fish Oil She also takes: miralax gabatril keppra She had more energy once they changed her supps that is for sure. They also had us take out all of the fat from her diet and all of the oil. If someone has a similar situation please email. I already love this group. Thank you and God Bless Christy Mom of 12, Connor 7 allergic to food dyes, and Molly Ann 2, CP, Microcephaly, Infantile Spasms and Mitochondrial Disorder Please contact mito-owner with any problems or questions.
