Trisomy 21 karyotype

[Article in Polish] Dorant B, Limon J, Martyńska L. The most common things doctors look for with karyotype tests include: Down syndrome (trisomy 21). A baby has an extra, or third, chromosome 21. This affects how the baby looks and learns. Mosaic Trisomy 21 – This is a rare form (less than 2% of cases) of Down syndrome. While similar to simple trisomy 21, the difference is that the extra chromosome 21 is present in some, but not all cells, of the individual. This type of Down syndrome is caused by abnormal cell division after fertilization.
