Abstract The cleavage stage embryo (days 1-3) stands out due to the high level of chromosomal anomalies, especially mosaicism that arises prior to global embryonic genome activation. Molecular cytogenetic studies show that an average of 60% of in vitro derived embryos have at least one aneuploid cell by the time they are 3 days old. No. 348-Joint SOGC-CCMG guideline: update on prenatal screening for fetal aneuploidy, fetal anomalies, and adverse pregnancy outcomes [published correction appears in J Obstet Gynaecol Can 2018;40 The previous molecular genetic analysis of chromosomal abnormalities arising from miscarriages showed that most aneuploid events occur during female meiosis, usually because of non-disection in the first meiotic division.


Our study showed that MCM and DWM each accounted for about 45% of fetuses with enlarged PF. In MCM and DWM there were 21 and 39% associated intracranial anomalies, respectively. About a third of the fetuses with MCM or DWM that were karyotyped were aneuploid.

Aneuploidi innebär en avvikelse av antalet kromosomer, från det normala hos en individ, vilket i regel orsakar sjukdom.Människan är diploid, det vill säga att celler har dubbla kromosomuppsättningar och varje avvikelse från detta innebär aneuploidi. Aneuploidy was significantly more common in fetuses who had a nuchal finding and an associated structural anomaly. The prevalence of nuchal fold and non-septated cystic hygroma, as well as the incidence of their associated structural anomalies, was similar. The cleavage stage embryo (days 1-3) stands out due to the high level of chromosomal anomalies, especially mosaicism that arises prior to global embryonic genome activation.

Aneuploid anomalies

Some anomalies, however, can happen after conception, resulting in Mosaicism (where some cells have the anomaly and some do not). Chromosome anomalies can be inherited from a parent or be "de novo". This is why chromosome studies are often performed on parents when a child is found to have an anomaly. Aneuploid conditions are often suspected by prenatal ultrasound (US) when multiple, and sometimes severe, structural anomalies are seen.

Aneuploidy is the leading contributor to pregnancy loss, congenital anomalies, and in vitro fertilization (IVF) failure in humans. Although most aneuploid conceptions are thought to originate from meiotic division errors in the female germline, quantitative studies that link the observed phenotypes to underlying error mechanisms are lacking.

For the assessment of the factors that could induce mosaicism, embryos were divided in two groups: mosaic embryos (euploid–aneuploid and aneuploid–aneuploid) and embryos with no mosaicism (euploid and aneuploid). lower (P=0.000001) compared to the induced abortions. Spontaneous abortions with aneuploid anomalies (monosomy X, trisomy 21, trisomy 16 and triploidy) were characterized by shorter telomeres, compared to spontaneous abortions, subgroup with euploid (46,XN) karyotype.
