Trisomy 21- mitotic nondisjunction mosaicism
WebFor trisomy 16, virtually all cases are due to maternal meiosis I non-disjunction. Postzygotic (mitotic) non-disjunction constitutes 5-15% of cases of trisomies 15, 18, and 21, whereas for trisomy 8 and trisomy 8 mosaicism the majority of cases are due to mitotic non-disjunction.

WebNov 12, 2024 · Trisomy 21 (Nondisjunction) Down syndrome is usually caused by an error in cell division called “nondisjunction.” Nondisjunction results in an embryo with three copies of chromosome 21 instead of the usual two. Prior to or at conception, a pair of 21st chromosomes in either the sperm or the egg fails to separate. WebBoth options 2 and 5 can produce a Down syndrome mosaic from a normal diploid zygote. Option 2, mitotic nondisjunction of chromosome 21, would occur after the zygote is formed and the resulting abnormal cell would have an extra copy of chromosome 21. If this abnormal cell continues to divide, it would create a population of cells with the extra ...
WebMosaicism syndromes can be caused by mitotic nondisjunction in early fetal development. As a consequence, the organism evolves as a mixture of cell lines with differing ploidy (number of chromosomes). Mosaicism may be present in some tissues, but not in others. Affected individuals may have a patchy or asymmetric appearance.
