What are some common chromosome abnormalities?

Down Syndrome

Open-uri20130408-18769-ntk69m
Trisomies (3 instead of 2 of a certain chromosome) are most common. Down is caused by an extra copy of chromosome 21. Patients usually have lower IQ, shortened lifespans and specific facial and anatomic features. Edwards Syndrome involves an extra copy of 18. The most common in utero is 16, though spontaneous miscarriage rates are very high. Patau syndrome (extra 13) also has a high mortality.

Are chromosomal abnormalities only confined to certain parts of your body?

No

Chromosomal_abnormalities
The typical chromosomal(CHM) defect shows up as abnormal CHM in every cell of your body. Some cells do little (skin just sits there) while others do a lot ( form the heart,hands,brain). The need for detail in complex parts means the defect will have more effect. Rare CHM defects produce a mosaic, where a fraction of the body has normal & others abnormal. Variable effect.
