An unusual case of Mosaic Down's Syndrome
scholar - 18-10-2008 at 18:10

I have been listening to a radio magazine account of a person named Tim with Mosaic Down's Syndrome. This was explained as a variation from the more common Down's Syndrome. In the Mosaic form, some of the cells have the Down's syndrome variation from birth, and some don't. When the parents first got the news, they couldn't know which characteristics would develop as a Down's syndrome person, and which would not. E.g. a person might look as a typical Down's syndrome person, but have more standard intellectual development. Or, he might not have the distinctive appearance at all, but have some of the other problems. All would depend which chromosomes predominate in which mature cells.

I had never heard of this condition. (Marymary, have you?. I don't know how rare it is.)

But, even more unusual than the condition, was the way Tim's parents decided to handle it, based on an idea from his mother.

The first year Tim was in school, his mother told the teacher of his medical condition. One day, the mother visited the school and saw the other students sitting and listening to the reading, while Tim was rolling around on the rug! :o The teacher said that Tim likes to do that, and she didn't want to make him sit still. Mother had the dread feeling that Tim would not develop to his potential, because the teachers would hold him to a lower standard. She also realized Tim, himself, might use it as an excuse to demand less of himself.

So, after a discussion with her husband, Mother decided to keep it private. She didn't tell the next teacher. She kept it secret from Tim. She warned the small number of people who knew about it of her plan, so they wouldn't mention it in front of Tim or outsiders.

And Tim grew up through childhood with a few Down's syndrome characteristics. His IQ was 110. He was held to the same standard as anyone else.

The one time in his boyhood that Mom was very tempted to tell him, was when little Tim excluded a Down's syndrome boy at play. But she held her piece.

Tim was 14 before he found out. A time came that he asked his mother if he had some secret medical condition that he didn't know about. Finally, she told him.

And he didn't get mad, or feel bad about it--he was relieved! With knowledge, he realized some things he did--like rocking on his heels--were things toward which he was predisposed, but which he could work on.

Since he found out, he has been more at ease with himself. He has had a better social life. He is now 20.
