Butterfly effect and autism spectrum disorder

A study conducted by researchers at the RIKEN Center for Brain Science (CBS) has shed light on the genetics of Autism Spectrum Disorder (ASD). They found that a particular type of genetic mutation contributes to ASD differently than typical mutations. By analyzing mutations in the genomes of individuals and their families, the researchers discovered that the three-dimensional structure of the genome can cause mutations to affect neighboring genes associated with ASD, even without mutations in ASD-related genes. The study was published in the scientific journal Cell Genomics on January 26. ASD is a group of conditions characterized by repetitive behaviors and social interaction difficulties. Although the condition runs in families, its heritability is complex and only partially understood. According to studies, the high heritability cannot be explained by merely looking at the part of the genome responsible for protein coding. Instead, the answer could lie in the non-coding regions of t...

Rethinking Cannabis: Unlocking the Genetic Blueprint of an Ancient Powerhouse

Cannabis has played a critical role in human societies for over ten millennia. Although contemporary attention often centers on its psychoactive component, THC (tetrahydrocannabinol), historically this plant served as an essential source of seed oil, textiles, and nourishment. Despite its longstanding significance, cannabis remains relatively underexplored and underexploited in modern agriculture. Recent legislative changes in the United States—most notably the 2014 and 2018 Farm Bills—have spurred renewed interest in cultivating cannabis for medicinal, grain, and fiber purposes. A team at the Salk Institute has now produced the most exhaustive and precise genetic atlas of cannabis to date. By examining 193 distinct cannabis genomes, researchers uncovered remarkable genetic diversity and complexity within this foundational crop. This collaborative effort involved Oregon CBD, Oregon State University, and the HudsonAlpha Institute for Biotechnology, and culminated in findings published i...

Understanding the Complex Interplay: Dementia and Genetic Changes

Introduction: Dementia is a challenging and multifaceted condition that affects millions of individuals worldwide. As our understanding of the factors contributing to dementia expands, one crucial aspect gaining attention is the role of genetic changes. This blog post aims to explore the intricate relationship between dementia and genetic factors, shedding light on the complexities of this neurological disorder. I. The Genetic Landscape of Dementia: Dementia encompasses a range of cognitive disorders, with Alzheimer's disease being the most prevalent form. While environmental factors and lifestyle choices play a role in dementia development, genetic changes are increasingly recognized as significant contributors. A. Familial Patterns: Research has identified certain familial patterns in dementia, indicating a genetic predisposition for some individuals. Families with a history of dementia may carry specific gene variants that increase the risk of developing the condition. Understan...

Autism and Eye Contact: Genes very much are involved

We have now a lot of evidence on genetic components in many disorders including neurological in both adults and kids. Autism is one such problem that has many genes involved. Research is still in full swing to find more genes and related pathways. However, one can find autistic features more phenotypically before genotyping. Eye contact is one of them. Studies have shown that autistic kids make less eye contact. This has been shown to have genetic component now. New research has uncovered compelling evidence that genetics plays a major role in how children look at the world and whether they have a preference for gazing at people's eyes and faces or at objects. The discovery by researchers at Washington University School of Medicine in St. Louis and Emory University School of Medicine in Atlanta adds new detail to understanding the causes of autism spectrum disorder. The results show that the moment-to-moment movements of children's eyes as they seek visual information about the...

Unraveling the Mysteries: Exploring New Genetic Variants Related to Dementia

Introduction: Dementia, a debilitating condition affecting millions worldwide, has long been a subject of intense research. Scientists and researchers have tirelessly worked towards understanding its underlying causes, and recent breakthroughs in genetics have brought forth new hope. This blog post delves into the latest discoveries surrounding genetic variants linked to dementia, shedding light on the potential implications for both diagnosis and treatment. The Human Genome Project and Beyond: Advancements in genetic research, particularly since the completion of the Human Genome Project, have paved the way for a deeper understanding of the intricate relationship between genes and various health conditions, including dementia. The identification of specific genetic variants associated with an increased risk of developing dementia has become a pivotal focus. Key Genetic Variants: Recent studies have unveiled several genetic variants implicated in the onset and progression of dementia. ...
