Identical twins with autism spectrum disorder (ASD) often experience large differences in symptom severity even though they share the same DNA, according to an analysis funded by NIH.

A small study by researchers at NIH suggests that mutations in the gene CABLES1 may lead to Cushing syndrome, a rare disorder in which the body overproduces the stress hormone cortisol.

A single protein allows mycobacteria to generate diverse populations that can avoid TB drugs. The protein may be a target for intervention; blocking it might result in less mycobacterial diversity and shorten TB treatment courses.

Baby teeth from children with autism contain more toxic lead and less of the essential nutrients zinc and manganese, compared to teeth from children without autism.

Cells within an injured mouse eye can be coaxed into regenerating neurons and those new neurons appear to integrate themselves into the eye’s circuitry, new research shows.

A new study suggests that T cells, which help the body’s immune system recognize friend from foe, may play an important role in Parkinson’s disease.

Researchers funded by NIH have developed a new imaging method that visualizes a very different DNA structure, featuring small folds of DNA in close proximity. The study reveals that the DNA-protein structure, known as chromatin, is a much more diverse and flexible chain than previously thought.

NIH researchers have discovered molecular mechanisms that may underlie a woman’s susceptibility to disabling irritability, sadness and anxiety in the days leading up to her menstrual period.

Investigators with the Cancer Genome Atlas (TCGA) Research Network have identified novel genomic and molecular characteristics of cervical cancer that will aid in the sub-classification of the disease and may help target therapies that are most appropriate for each patient.

Children of obese parents may be at risk for developmental delays, according to a study by researchers at NIH.
