Post-zygotic variation refers to genetic changes that arise in the soma of an individual and
that are not usually inherited by the next generation. Although there is a paucity of research …

The mechanisms responsible for twinning and disorders of twin gestations have been the
subject of considerable interest by physicians and scientists, and cases of atypical twinning …

Buccal swabs and saliva are the two most common oral sampling methods used for medical
research. Often, these samples are used interchangeably, despite previous evidence that …

Human pluripotent stem cells (hPSCs) are known to acquire genomic changes as they
proliferate and differentiate. Despite concerns that these changes will compromise the safety …

Non-invasive prenatal testing (NIPT) by random massively parallel sequencing of maternal
plasma DNA for multiple pregnancies is a promising new option for prenatal care since …

With the introduction of increasingly sensitive technologies for mutation detection such as
chromosomal microarrays and next‐generation sequencing, the importance of mosaicism …

Objective: The purpose of this article is to review the definition of twin-to-twin transfusion
syndrome (TTTS) and the sonographic diagnostic assessment of these cases prior to …

Traditionally, it is understood that dizygotic (DZ) twins always have a dichorionic placenta.
However, with 8% blood chimerism in DZ twins, placental sharing is probably more common …

Sesquizygotic multiple pregnancy is an exceptional intermediate between monozygotic and
dizygotic twinning. We report a monochorionic twin pregnancy with fetal sex discordance …

Abstract Analysis of biological mixtures is a significant problem for forensic laboratories,
particularly when the mixture contains only one cell type. Contributions from multiple …
