Gypsy Rose Blanchard revealed that her daughter, Aurora, tested negative for 1q21.1 microdeletion, which is a genetic condition that she has. In light of the announcement, many people are wondering ...

Autism and mental retardation (MR) show high rates of comorbidity and potentially share genetic risk factors. In this study, a rare ∼2 Mb microdeletion involving chromosome band 15q13.3 was detected ...

You might know that some prenatal tests screen for Down syndrome and other chromosomal disorders, but you may not have heard of microdeletions. This type of chromosomal disorder is more common than ...

In a recent study published in the Genes journal, researchers assessed the impact of PARK2 duplication or microdeletion on neurological diseases such as Parkinson's. The Parkinson's disease 2 (PARK2) ...

Researchers are closer to solving the puzzle of a complex neurological condition called 15q13.3 microdeletion syndrome. Individuals with this condition are missing a small piece of chromosome 15 that ...

Numerous studies have shown that segmental duplications and the flanking unique regions are sites of both rare and common copy-number polymorphism (CNP) 1,2,3. Segmental duplications are blocks of DNA ...

Researchers are closer to solving the puzzle of a complex neurological condition called 15q13.3 microdeletion syndrome. Individuals with this condition are missing a small piece of chromosome 15 that ...

The definitive diagnosis of fetal aneuploidy and genomic imbalances requires invasive collection of fetal cells through amniocentesis or chorionic villus sampling. These methods are associated with ...

Some of the tests look for missing snippets of chromosomes. For every 15 times they correctly find a problem ... … they are wrong 85 times By Sarah Kliff and Aatish ...
