What are the Stages of Alzheimer’s Disease? – Medical News Today

Originally posted 2017-01-12 15:48:00.

Alzheimer’s disease is a progressive degenerative disorder that becomes worse over time. It involves a gradual loss of memory, as well as changes in behavior, thinking, and language skills.Although every person experiences Alzheimer’s differently, the way in which the disease progresses can be grouped into a series of stages.It is important to make sure that someone with dementia lives well with the condition and that their needs are met, rather than focusing on what stage they might be in.

Reverse Pathway Genetic Approach Identifies #Epistasis in #Autism Spectrum Disorders

Originally posted 2017-01-12 15:35:57.

Although gene-gene interaction, or epistasis, plays a large role in complex traits in model organisms, genome-wide by genome-wide searches for two-way interaction have limited power in human studies. We thus used knowledge of a biological pathway in order to identify a contribution of epistasis to autism spectrum disorders (ASDs) in humans, a reverse-pathway genetic approach. Based on previous observation of increased ASD symptoms in Mendelian disorders of the Ras/MAPK pathway (RASopathies), we showed that common SNPs in RASopathy genes show enrichment for association signal in GWAS (P = 0.02). We then screened genome-wide for interactors with RASopathy gene SNPs and showed strong enrichment in ASD-affected individuals (P < 2.2 x 10−16), with a number of pairwise interactions meeting genome-wide criteria for significance. Finally, we utilized quantitative measures of ASD symptoms in RASopathy-affected individuals to perform modifier mapping via GWAS. One top region overlapped between these independent approaches, and we showed dysregulation of a gene in this region, GPR141, in a RASopathy neural cell line. We thus used orthogonal approaches to provide strong evidence for a contribution of epistasis to ASDs, confirm a role for the Ras/MAPK pathway in idiopathic ASDs, and to identify a convergent candidate gene that may interact with the Ras/MAPK pathway.

Study details molecular roots of #Alzheimer’s

Originally posted 2017-01-11 09:20:14.

Scientists at Washington University School of Medicine in St. Louis have detailed the structure of a molecule that has been implicated in Alzheimer’s disease. Knowing the shape of the molecule—and how that shape may be disrupted by certain genetic mutations—can help in understanding how Alzheimer’s and other neurodegenerative diseases develop and how to prevent and treat them.
