Hi, I'm hoping someone might have some insights into this so I can better decide on further testing for my child.
Back in 1973 my parents seeded the lawn at our new house and put my brand new swingset in the garage for the @ 2weeks for the grass to grow. I was told I could not touch the swing set until it was out of the garage. I was 4, of course I didn't listen, snuck in and started climbing on it. I fell and suffered a hairline skull fracture approximately 2 inches above my right ear. I was in and out of consciousness but my Mom does not remember the doctor saying anything about hematomas and I did not have a surgery of any kind. I spent 7 days in the hospital and was sent home with just orders to "keep her quiet". The doctor said I had small muscle coordination impairment from the fracture, that it appeard to slightly affect my speech and I may or may not outgrow it. My speech is normal but I do have problems with fine motor movements, especially on my left side. I am very right hand dominate and have been my whole life.
Now to current times. My youngest son was diagnosed in January of 2009 with Childhood apraxia of speech. This is a neurologically based motor planning disorder which severly affects a childs ability to talk. It can also affect a child globally causing motor planning problems in both gross and fine motor planning. Will has all three with speech being the most affected and with gross motor incoordination being next. He has "failed to progress" in fine motor skills the last 2 years and is now below normal for age despite 2 years of a developmental delay preschool that focused on using those skills.He's 5. There is some evidence that Childhood apraxia of speech is at least partly genetic but no particular genes have been identified. FoxP2 is the most likely but no proof.
My question is this. Is it really likely that a hairline skull fracture could have caused my problems post fracture to the present day? Or is it more likely that I have a very mild version of what my son has? There is no other family history of this disorder and I'm wondering if it would really be worthwhile to go to the expense of genetic testing. If my problems were truely likely to have been caused by a fall then Will is most likely completely ideopathic and genetic testing probably won't reveal anything usefull. If it's unlikely then genetic testing of him, myself and other members of our immediate family may at least show chromosomal problems that we may need to watch for in the future and may give him something to have his children tested for to get them intervention earlier.
