My son has a splice site mutation in Intron 46. IVS46-2A>G is the specific mutation code. I guess its a substitiution mutation. Has anyone else had a splice site mutation and in an INTRON? The neuro told us it was extremely rare and they want to do a muscle biopsy to look at his muscles to see and give us a prognosis. At this time they do think its BMD due to lower CK levels and an MRI that really showed nothing but a few areas in his buttocks region which was good news. Anyone know of any trials for my sons type mutation? Thanks!

Hey Stacy I have never heard of this. I think your best bet is to work with the genetic folks that are deep in this stuff and may know of others that are similar. It definitely is not a run of the mill genetic issue. The University of Utah is one of the leaders in MD genetic research and study and may be most helpful Kevin Flanigan is the guy to talk with. BTW: Kevin Flanigan will be at the BMD conference in Boston in August. Kevin

I took your advice and contacted Dr. Kevin Flanigan. Once he receives my reports and looks them over he agreed to speak with me. Hopefully I can learn a great deal about the mutation my son has. I just learned that I am a carrier of this mutation. Floored me since no one in my family has ever had the disease. Brought up a whole new set of issues with my other children. With Nicholas's mutation there were also several other hemizygous sequence variants detected. The report said they were found in patients and unaffected individuals, and are interpreted as unlikely to be related to disease. But since I know I am a carrier, I wonder if this has problems for my other children as well. Can you shed some light on this at all? What can you tell me about a splice site mutation or an intron for that matter. I feel so in the dark about all of this. Its a lot to handle all at once. His sequence analysis said it had not been reported but is likely to alter normal splicing and thus, it is considered to be a disease causing mutation. About the conference.....Do they charge for these and how do you RSVP?

Hey Stacy The conference is free. Dr. Flanigan will be the best source for your questions about the genetics. This is such a rare situation that I can't offer you any guidance. Kevin
