Surprising contributor to Rett syndrome identified

The immune system is designed to protect us from disease. But what if it was malfunctioning? Would it make a disease worse? That appears to be the case with Rett syndrome, a neurodevelopmental disorder, and possibly in other ...

Genetics

Rett syndrome may result from overexpression of long genes

Mutations in the methyl CpG binding protein 2 gene (MECP2) are the cause of the devastating childhood neurological disorder Rett Syndrome. Despite intense efforts spanning several decades the precise function of MECP2 has ...

Multiple models reveal new genetic links in autism

With the help of mouse models, induced pluripotent stem cells (iPSCs) and the "tooth fairy," researchers at the University of California, San Diego School of Medicine have implicated a new gene in idiopathic or non-syndromic ...

Rett syndrome drug shows promise in clinical trial

Rett syndrome, a rare genetic disorder that causes mental retardation, autism, and physical deformities, has no cure. However, a small clinical trial has found that a growth factor known as IGF1 can help treat some symptoms ...

Neuroscience

Permanent changes in brain genes may not be so permanent after all

In normal development, all cells turn off genes they don't need, often by attaching a chemical methyl group to the DNA, a process called methylation. Historically, scientists believed methyl groups could only stick to a particular ...
