The pitfalls of PGT-A and scoring of mosaic embryos

Preimplantation genetic testing for aneuploidies (PGT-A) or formerly known as preimplantation genetic screening (PGS), is genetic testing for numerical (aneuploidy) and structural chromosomal aberrations in IVF-embryos. Most aneuploidies including several structural chromosomal aberrations are not compatible with

Chromosome gains and losses in the human brain are probably less important than previously thought

In general, each human cell contains 46 chromosomes: 23 chromosomes from each parent. Before a cell divides all chromosomes are duplicated. The cell has several mechanisms to ensure that during cell division the chromosomes are evenly distributed
