Trisomy 13 mosaicism mitotic nondisjunction

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 …

WebTrisomy 21 is the cause of approximately 95% of observed Down syndrome, with 88% coming from nondisjunction in the maternal gamete and 8% coming from nondisjunction in the paternal gamete. [4] Mitotic nondisjunction after conception would lead to mosaicism, and is discussed later. WebTo investigate the different timings and nature of chromosomal mosaicism, we developed single cell multiplex fluorescent (FL)-PCR to distinguish meiotic and mitotic cell division errors. Chromosome 21 was investigated as the model chromosome as trisomy 21 (Down's syndrome) represents the most common chromosomal aneuploidy that reaches live birth.

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.
