People with Prader-Willi syndrome often experience behavioral problems, such as angry outbursts, physical aggression, manipulative behavior, stubbornness, and compulsive behaviors such as skin picking ...

The smaller inv dup (15), on the left, is not associated with phenotypic abnormalities, whereas the larger inv dup (15), on the right, is associated with an abnormal phenotype (the central two are ...

DENVER -- Genetic testing and algorithms revealed that over 1% of more than 96,000 blastocyst-stage embryos had ploidy abnormalities, or atypical numbers of chromosomes. In total, ploidy ...

Since several of those conditions involve deletions or duplications of chromosomal segments – including an inherited deletion of a region of chromosome 15 – the investigators conducted a ...

Two de novo abnormal derivatives of chromosome 15, inv dup (15) and dup (15q) were found in a girl with developmental delay and mild dysmorphological signs. Fluorescence in situ hybridization ...

The q arm of chromosome 21 appears to carry the genetic material that causes the Down syndrome manifestations. These children have serious anomalies of the heart, intestines, and spine.

Chromosomal abnormalities are differences in the chromosomes that can happen during embryonic and fetal development. They could be "de novo" (unique to the fetus) or inherited from a parent.
