Leaky mitochondria may play central role in fragile X syndrome
Some traits of fragile X syndrome may be due to problems with mitochondria, the cell’s energy factories.

Mice that lack a segment of chromosome 22 — a mutation associated with autism — have unusually sparse connections between brain regions.
Problems with the minute ‘factories’ that yield energy for cells — the mitochondria — may contribute to learning problems and other traits of fragile X syndrome.
A researcher proposes splitting autism into subtypes, mitochondria make neurotransmitters, and highly successful grantees may face a funding cap.
Genetic variants that affect mitochondria, the organelles that power cells, may increase the risk of autism.
Women describe relief at finally learning they have autism, a man with epilepsy narrates during stimulation of his brain, and the brain’s immune cells are caught on film nibbling at neuronal connections.
Researchers find a surprising link between certain pollutants and reduced autism risk, the world welcomes — and fears — the first primate clones, and new U.S. clinical trial rules reverberate globally.
Some variants in mitochondrial DNA are more common than others in autism, cognitive therapy reduces anxiety for people on the spectrum, and maternal fever in the third trimester is tied to autism risk.
A drug normally used to treat African sleeping sickness had only mild side effects in a widely reported trial of 10 boys with autism — but researchers question the study’s premise.
Variants of some mitochondrial genes may contribute to autism — in some cases, by teaming up with genes in the nucleus.
