File photo of in-vitro fertilisation, in which eggs were harvested from a woman’s ovaries, fertilised, and then cryogenically preserved. (Photo: AFP) ATHENS: A team of Greek and Spanish doctors announced Thursday (Apr 11) the birth of a baby using DNA from three people after a controversial fertility treatment that has provoked intense ethical debate. The team … Read more
Hirschsprung disease – a rare condition where the failure of gut nerves to develop before birth leads to impaired bowel contractions that prevent infants from passing stool – is more predictable from an individual's genetic makeup than previously envisioned. This is the finding of a study published online in the April 11 edition of the … Read more

The team used an egg from the infertile mother, the father’s sperm and another woman’s egg to conceive the baby boy, … Read more
Scientists at UMass Medical School have developed a strategy for editing and repairing a particular type of genetic mutation associated with microduplications using CRISPR/Cas9 and a seldom-used DNA repair pathway. Described in Nature, this approach to programmable gene editing overcomes prior inefficiencies in gene correction. "It's like hitting the reset button," said Scot A. Wolfe, … Read more
A new study looks at the genetic makeup of thousands of adults with depression to try to find an accurate way of predicting which children and adolescents may be at risk of developing this mental health problem. Researchers identify a genetic risk score that could help predict depression risk in the young. Many factors determine … Read more
In cancer research, scientists usually look for cancer genes by scouring the genome for altered sequences — or mutations — in DNA. But a new study has now revealed that jumping genes, which customary sequencing overlooks, are also important drivers of tumor growth.Researchers have uncovered 129 jumping genes that may drive cancer. Scientists at the … Read more
Genetic compensation does not appear in the absence of mutant mRNA. The figure shows the vascular system in a two-day old zebrafish embryo. When the mRNA derived from a defective gene is absent, the vascular system does not develop properly (lower image). Credit: MPI for Heart and Lung Research. Many diseases are caused by genetic … Read more
