Brogan 4 1/2 months Family doesn't know what Down Syndrome is and want to know what kind? They really are asking "what's the severity?"
Well for every kid it's different. But, this is what I've read:
2.1 Trisomy 212.2 Mosaicism2.3 Robertsonian translocation2.4 Duplication of a portion of chromosome 21Brogan has Trisomy 21. So whatever type Brogan has - he is missing a lot of the typical features of Down Syndrome that doctors look for.
Definition of Down syndrome features
Down syndrome features: Children with
Down syndrome have multiple malformations and mental impairment due to the presence of extra material from
chromosome 21.
Among the more common physical features are
hypotonia (floppiness), small head with
brachycephaly, epicanthic folds across the inside corners of the eyes, upward outward slanting palpebral fissures (eye slits), Brushfield spots in the
iris, small mouth, small ears, excessive skin at the nape of the neck, a single transverse
palmar crease, and short fifth finger with
clinodactyly (incurving). A wide space, often with a deep fissure between the first and second toes, is also common.
There is an increased risk of
congenital heart defects (50%);
leukemia (<1%);
Hirschsprung disease with absence of nerves from the bowel (
atresia (12%); eye disease (60%), including cataracts (15%) and severe refractive errors (50%); acquired hip dislocation (6%); obstructive sleep apnea (50%-75%); and thyroid disease (15%). There is no increased risk of solid tumors.
There is mental impairment. The degree is variable, ranging from mild (IQ: 50-70) to moderate (IQ: 35-50), and only occasionally to severe (IQ: 20-35).
The social quotient may be improved with early intervention techniques, although the level of function is exceedingly variable. Children with Down syndrome often function better in social situations than might be expected from their IQ.
An excellent set of guidelines for the health care of children with Down syndrome is available from the American Academy of Pediatrics.

I told Dusty that instead of rating as a genius he's probably have to settle for normal. Dusty scored two points below the IQ requied for MENSA.
