random chromosome abnormalities, or embryonic aneuploidy is screened for more often now. The cause of miscarriage is often aneuploidy but so far, there is no genetic part he showed that ultrasound can give false positive diagnosis of fetal anomalies.

The request for transfer of aneuploid embryos (embryos with chromosomal abnormalities) is one such dilemma. While the goal of in-vitro fertilization (IVF) and preimplantation genetic testing for aneuploidy (PGT-A) is typically to achieve a pregnancy with a euploid (chromosomally normal) embryo, infrequently, a patient might request transfer of an aneuploid embryo. 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".

Aneuploid conditions are often suspected by prenatal ultrasound (US) when multiple, and sometimes severe, structural anomalies are seen. Different aneuploid conditions are typically associated with specific constellations of US findings. US on its own, however, is an insufficient screening tool for aneuploidy.

L'aneuploïdie caractérise une cellule qui ne possède pas le nombre normal de chromosomes.Plus spécifiquement, cette anomalie chromosomique est caractérisée par un nombre de chromosomes qui n'est pas un multiple du nombre haploïde (nombre normal d'un seul jeu complet de chromosomes) [1].

Some cancer cells also have abnormal numbers of chromosomes. About 68% of human solid tumors are Aneuploidy is a chromosomal anomaly in which the number of one or more chromosomes is abnormal. Normal human somatic cells (i.e., nonegg or sperm cells) carry 46 chromosomes: two copies of each of the 22 autosomal chromosomes and two sex chromosomes, either XX for female or XY for male. Most aneuploid disorders arise from additions or deletions of chromosomal pieces, rather than the duplication or loss of an entire chromosome [C].

Aneuploi US findings vary for the different aneuploidy syndromes: Sonographic findings in fetuses with trisomy 21 include thickening of the nuchal fold, cardiac abnormalities, duodenal Trisomy 18 is associated with abnormal hand positioning (a “clenched hand” appearance with the index finger Aneuploidy refers to an abnormal number of chromosomes, and is a type of chromosomal abnormality.There are large number potential aneuploidic anomalies. The most common three in obstetric practice are: trisomy 21: commonest aneuploidic anomaly Cardiovascular anomalies were the most commonly detected structural malformations. Forty-three (3.4 per cent) fetuses were aneuploid.

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. 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. 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. Kromosomförhållande i celler som avviker från det normala genom övertalighet eller förlust av kromosomer eller kromosompar. Meiosis is essential for creating gametes required for sexual reproduction.

Aneuploidy is the presence of an abnormal number of chromosomes in a cell, for example a human cell having 45 or 47 chromosomes instead of the usual 46. It does not include a difference of one or more complete sets of chromosomes.
