Summary: Researchers identified variants in the DDX53 gene, located on the X chromosome, as contributors to autism spectrum disorder (ASD). These genetic variants, found predominantly in males, provide critical insights into the biological mechanisms behind autism’s male predominance.The study also uncovered another potential gene, PTCHD1-AS, near DDX53, linked to autism,...

Summary: Scientists have developed human stem cell models containing the notochord, a critical tissue that guides spine and nervous system formation during embryonic development.Using precise chemical signals inspired by natural processes in chicken, mouse, and monkey embryos, the researchers successfully coaxed human stem cells to form a notochord and a...
