Ideograms and partial karyotypes are shown. For the deletions, the arrows indicate a) the deletion of chromosome 15q11-13 associated with Prader-Willi and Angelman syndromes, and b) the deletion of ...

A mother-of-four from Cradley Heath, near Birmingham, has spoken of her two-year-old daughter's diagnosis with an extremely rare disorder, discovered by chance during an unrelated hospital visit.

Esotropia and exotropia could have shared genetic risk factors based on findings that genetif duplications on chromosomes were risk factors for the diseases. Genetic duplications in the second, fourth ...

Scott W. Stuart, MD, MS; Casey H. King, BA; G. Shashidar Pai, MD Such observations emphasize the importance of clarifying the origin of a genetic variation by studying the parents for comparison. The ...

A newborn male with Fryns syndrome (FS), a lethal autosomal recessive condition, also had mosaic tandem duplication of chromosome 1q. Multiple malformations were noted at birth including diaphragmatic ...

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) ...

The cost of raising a child with a rare genetic disorder was significant but the economic burden could be reduced by earlier diagnosis and targeted treatment, a new study has found. The research, led ...

Cell biologists have found a key clue in the mystery of how chromosomes are inherited correctly every time a cell divides. Using a novel cell probe, they unraveled how a 'matchmaker' molecule stops ...

The effects of chromosome rearrangement on genome size are poorly understood. While chromosome duplications and deletions have predictable effects on genome size, chromosome fusion, fission, and ...

Large blocks of genes conserved through hundreds of millions of years of evolution hint at how the first animal chromosomes came to be. Chromosomes, the bundles of DNA that star in the mitotic ballet ...

Autism spectrum disorders are heterogeneous in nature with idiopathic and genetic origins. We present a 7-year-old boy with a long history of multiple behavioral concerns, poor school performance, ...
