Mechanism preserving genome integrity help develop new therapies against DiGeorge syndrome

An international team of scientists-including researchers at GENYO, the Centre for Genomics and Oncological Research (Pfizer-University of Granada- Andalusian Regional Government)-has described a molecular mechanism that facilitates the defence of the human genome against "bombarding" by mobile DNA sequences.

Chromosome 22q11.2 deletion syndrome anxiety linked to poorer adaptive behaviors

UC Davis researchers have found that for children with the genetic disorder known as chromosome 22q11.2 deletion syndrome anxiety -- but not intelligence -- is linked to poorer adaptive behaviors, such as self-care and communication skills, that affect daily life. The developmental syndrome, which is associated with a constellation of physical, cognitive and psychiatric problems, usually is apparent at birth or early childhood, and leads to lifelong challenges.

Thymus tissue, iPSCS and liver cells can thrive in lymph nodes

Lymph nodes can provide a suitable home for a variety of cells and tissues from other organs, suggesting that a cell-based alternative to whole organ transplantation might one day be feasible, according to researchers at the University of Pittsburgh School of Medicine and its McGowan Institute for Regenerative Medicine.

MOZ protein could explain variations in severity of DiGeorge syndrome

The discovery of a 'switch' that modifies a gene known to be essential for normal heart development could explain variations in the severity of birth defects in children with DiGeorge syndrome.

Associate director of Clinical Genetics receives Angelo DiGeorge Medal of Honor

Donna McDonald-McGinn, M.S., CGC, associate director of Clinical Genetics and program director of the "22q and You" Center at The Children's Hospital of Philadelphia, received the Angelo DiGeorge Medal of Honor on July 6 at the 8th Biennial International 22q11.2 DS Conference in Lake Buena Vista, Florida. Ms. McDonald-McGinn, who began her career at CHOP in 1985, is the second person to receive this highly esteemed honor.

Researchers use maternal blood sample to sequence genome of an unborn baby

Researchers at the Stanford University School of Medicine have for the first time sequenced the genome of an unborn baby using only a blood sample from the mother.

Children with craniofacial disorders face numerous medical challenges beyond appearance

Children born with cleft lip, cleft palate and other craniofacial disorders face numerous medical challenges beyond appearance.

CHOP, Albert Einstein College of Medicine to study genetics of conotruncal defects

The Eunice Kennedy Shriver National Institute of Child Health & Human Development, part of the National Institutes of Health, has awarded researchers at Albert Einstein College of Medicine of Yeshiva University and collaborators at the Children's Hospital of Philadelphia (CHOP) a five-year, $6.7 million grant to study the genetics of both rare and common congenital heart abnormalities known as conotruncal defects.

New research provides insight into mechanism behind cardiac development

During embryonic development, cells migrate to their eventual location in the adult body plan and begin to differentiate into specific cell types. Thanks to new research at the University of Pennsylvania, there is new insight into how these processes regulate tissues formation in the heart.

Research sheds light on early embryogenesis, genetic disease

Chromosome 22q11 deletion syndrome (also known as DiGeorge syndrome) is the most common human chromosome deletion syndrome, having an estimated incidence of at least one in 4,000 live births.

Research sheds light on prenatal heart formation, chromosome 22q.11 deletion syndrome

Researchers studying the common genetic disorder chromosome 22q.11 deletion syndrome have identified key proteins that act together to regulate early embryonic development. One protein is essential to life; in animal studies, embryos without the protein do not survive past the first few days of gestation.

Researchers find the genetic mutation that is linked with changes in brain development

For decades, scientists have thought the faulty neural wiring that predisposes individuals to behavioral disorders like autism and psychiatric diseases like schizophrenia must occur during development. Even so, no one has ever shown that a risk gene for the disease actually disrupts brain development.

Absence of ERK2 gene linked to birth defects

A multidisciplinary research team at Case Western Reserve University led by Gary Landreth, Ph.D., a professor in the School of Medicine's Department of Neurosciences, has uncovered a common genetic pathway for a number of birth defects that affect the development of the heart and head. Abnormal development of the jaw, palate, brain and heart are relatively common congenital defects and frequently arise due to genetic errors that affect a key developmental pathway.

Scientists gain new insight into DiGeorge syndrome

A collaboration of European scientists has uncovered new insight into the most common chromosomal microdeletion syndrome in humans.

Researchers trim count of human genes to 20,000-25,000

Scientific description of the finished human genome sequence, reducing the estimated number of human protein-coding genes from 35,000 to only 20,000-25,000, a surprisingly low number for our species.
