GeneDx provides testing for autism spectrum disorders, various forms of cardiomyopathy, inherited eye, skin, muscle, hearing, metabolic, neurologic, and mitochondrial disease. [ citation needed ] GeneDx settled a patent dispute with Myriad Genetics in February 2015 after GeneDx launched a BRCA mutation breast cancer genetic screening test ...
The prevalence estimates of mitochondrial disease and dysfunction across studies ranging from about 5 to 80%. This may be, in part, due to the unclear distinction between mitochondrial disease and dysfunction. Mitochondrial diseases are difficult to diagnose and have become better known and detected.
The amygdala, cerebellum, and many other brain regions have been implicated in autism. [15]Unlike some brain disorders which have clear molecular hallmarks that can be observed in every affected individual, such as Alzheimer's disease or Parkinson's disease, autism does not have a unifying mechanism at the molecular, cellular, or systems level.
Robert K. Naviaux (born in 1956) is an American physician-scientist who specializes in mitochondrial medicine and complex chronic disorders. He discovered the cause of Alpers syndrome, [1] [2] and was part of the team that reported the first mitochondrial DNA (mtDNA) mutation to cause genetic forms of autism. [3]
Process for screening and diagnosing ASD; M-CHAT is Modified Checklist for Autism in Toddlers; (+) is positive test result; (−) is negative test result. There are several factors that make autism spectrum disorder difficult to diagnose. First off, there are no standardized imaging, molecular or genetic tests that can be used to diagnose ASD. [4]
Twin studies provide a unique opportunity to explore the genetic and environmental influences on autism spectrum disorder (ASD). By studying identical twins, who share identical DNA, and fraternal twins, who share about half of their DNA, researchers can estimate the heritability of autism by comparing the rates of when one twin is diagnosed with autism while the other is not in identical vs ...
Richard Eugene Frye is an American autism researcher and associate professor at Arizona Children's Hospital in Phoenix, and formerly of the University of Arkansas for Medical Sciences's department of pediatrics, [1] as well as the Director of the Autism Multispecialty Clinic at Arkansas Children’s Hospital.

Furthermore, low levels of BCAA have been described as a cause of comorbid intellectual disability, autism, and epilepsy. [ 8 ] Deficiency of BCKDK , first described in 2012, [ 11 ] is a disorder that could be considered as the "opposite" of maple syrup disease, because patients have decreased levels of branched-chain amino acids, instead of ...
