Scientists discover greater rates of mitochondrial mutations in children born to older mothers

A  normal mitochondria (left) contain distinctive folds known as cristae, but these folds are lost in damaged or dysfunctional mitochondria (right).

A team of Penn State scientists have discovered a “maternal age effect” that could be used to predict the accumulation of mitochondrial DNA mutations in maternal egg cells — and the transmission of these mutations to children — could provide valuable insights for genetic counseling. These mutations cause more than 200 diseases and contribute to others such as diabetes, cancer, Parkinson’s disease, and Alzheimer’s disease.

New Era of Designer Babies with Three Parents and No Hereditary Diseases

How the new designer babies are made.

Dozens of human embryos with three parents have been created by British scientists, ushering in an era of designer babies.  The embryos – which effectively have two mothers and one father – have been genetically engineered to be free from incurable muscle, brain, heart and digestive illnesses, some of which kill within hours of being born.
