Autism News and Research

RSS

Autism (sometimes called “classical autism”) is the most common condition in a group of developmental disorders known as the autism spectrum disorders (ASDs). Autism is characterized by impaired social interaction, problems with verbal and nonverbal communication, and unusual, repetitive, or severely limited activities and interests. Other ASDs include Asperger syndrome, Rett syndrome, childhood disintegrative disorder, and pervasive developmental disorder not otherwise specified (usually referred to as PDD-NOS). Experts estimate that three to six children out of every 1,000 will have autism. Males are four times more likely to have autism than females.

Developing a Fluorescent Sensor to Visualize Neuronal Self-Connectivity

How do brain cells, or neurons, distinguish their own processes and those of other neurons when they send out processes to connect with other neurons? A molecule known as clustered protocadherin (Pcdh) plays an important role in this puzzle.

Review: Role of Alternative Splicing Defects in Major Neurodegenerative Diseases

Alternative splicing, a clever way a cell generates many different variations of messenger RNAs -; single-stranded RNAs involved in protein synthesis -; and proteins from the same stretch of DNA, plays an important role in molecular biology.

Revealing How Human Brains Encode and Retain Value-Based Information

Researchers from the Center for Cognition and Sociality (CCS) within the Institute for Basic Science (IBS) recently announced the discovery of neurons that allow us to recognize others. The research team discovered that the neurons that deal with the information associated with different individuals are located in the CA1 region of the hippocampus.

Stimulating Cell DNA Repair Processes to Combat the Root Cause of Autism Spectrum Disorders

A new treatment option has been discovered for fragile X syndrome, which is the most common genetic cause of autism spectrum disorders and is defined by a hereditary repetition of certain nucleotides in the DNA sequence of the FMR1 gene. Researchers at Massachusetts General Hospital (MGH) carried out the study, which was published in the journal Cell.

Study Sheds Light on How Foxp2 Gene Controls the Ability to Produce Speech

Mutations of a gene called Foxp2 have been linked to a type of speech disorder called apraxia that makes it difficult to produce sequences of sound. A new study from MIT and National Yang Ming Chiao Tung University sheds light on how this gene controls the ability to produce speech.

STING-seq Discovers Causal Variants and Genetic Mechanisms for Blood Cell Traits

A major challenge in human genetics is understanding which parts of the genome drive specific traits or contribute to disease risk. This challenge is even greater for genetic variants found in the 98% of the genome that does not encode proteins.

Study Finds Link Between Chemical "Marks" on DNA in Father’s Sperm and Autistic Traits in Children

Among families with children diagnosed with autism spectrum disorder, Johns Hopkins University researchers say they have found a link between chemical "marks" on DNA in the sperm of fathers and autistic traits in their 3-year-old children.

DSCAM Gene Triplication Causes Excessive Inhibitory Signaling in the Brain of Down Syndrome Mouse

An extra copy of a gene that controls synapse formation in the cortex causes excessive inhibitory signaling and may contribute to Down syndrome, according to a new study publishing April 20th in the open access journal PLOS Biology by Bing Ye of the University of Michigan, US, and colleagues.

The Relation Between an Autism Gene and Infertility

The biological foundations of a reproductive disease caused by a DNA mutation have been discovered by a University of California, Riverside study. Fragile X Syndrome, a major genetic contributor to cerebral impairment and autism, is also caused by this gene mutation.
