Autism is a prevalent neurodevelopmental condition, highly heterogenous in both genotype and phenotype. This communication adds to existing discussion of the heterogeneity of clinical sequencing tests, "gene panels", marketed for application in autism. We evaluate the clinical utility of available gene panels based on existing genetic…

The gut microbiota was reported to differ between children with autism spectrum disorder (ASD) and typically developing (TD) children, and dysbiosis of the gut microbiota in preterm infants is common. Here, we explored the characteristics of gut microbiota in children born preterm with ASD. We performed 16S rRNA gene sequencing using stool samples…

Genotyping real alleles in real people is an excellent way to connect abstract genetics concepts to human variation in the classroom; however, these activities can inadvertently promote misconceptions of the power of genetics to determine individual and group traits. By analyzing our own and others' experiences of genotyping activities in the…

DNA-functionalized gold nanoparticles (DNA-AuNPs) have become a popular science theme since their invention in 1990s. They impact our daily lives by playing key roles in rapidly identifying and quantifying important analytes, and are a well-suited chemistry course content for beginners of chemical research. While the salt-aging method represents…

CRISPR-Cas9 technology is an established, powerful tool for genome editing through the ability to target specific DNA sequences of interest for introduction of desired genetic modifications. CRISPR-Cas9 is utilized for a variety of purposes, ranging from a research molecular biology tool to treatment for human diseases. Due to its prominence…

Exposure to environmental pollutants has been associated with cellular aging in children and adolescents. Individuals may vary, however, in their sensitivity or vulnerability to the effects of environmental pollutants. Larger hippocampal volume has emerged as a potential index of increased sensitivity to social contexts. In exploratory analyses…

Motor skills, an important foundation for language and communication, are considerably delayed in children with Down syndrome (DS) and fragile X syndrome (FXS). However, the impact of these impairments on expressive and receptive communication and the phenotypic specificity of these associations remains unknown. Participants included 37 with DS…

Genetic testing is recommended as part of an autism assessment, and most parents support genetic testing for their minor children. However, the impact on parents of receiving a monogenetic/ copy number variant diagnosis for autism in their child is not well understood. To explore this, we surveyed and interviewed parents of children in the SPARK…

The complexity of RNA cannot be fully expressed with the canonical A, C, G, and U alphabet. To date, over 170 distinct chemical modifications to RNA have been discovered in living systems. RNA modifications can profoundly impact the cellular outcomes of messenger RNAs (mRNAs), transfer and ribosomal RNAs, and noncoding RNAs. Additionally, aberrant…

Autism is associated with genomic instability, which is regulated by telomere length (TL) and index of global methylation (LINE-1). This study will determine relative TL (RTL) and LINE-1 methylation percentage for 69 patients and 33 control subjects to evaluate their potential role as biomarkers for autism. The results displayed a significant…

Recent studies show that oxidative stress has an important role in the etiology of autism. In our study, Nrf2, which is the main regulator of cellular antioxidant response, and Keap1 and Gsk-3[beta], which are the main proteins that regulate this pathway, were compared between children with autism and healthy controls. To the best of our…

Genetically modified organisms (GMOs) and their uses are often misunderstood. Consumers are regularly unsure what GMOs are, or if they are safe for consumption and the environment. Contradictory and sometimes inaccurate information is available from numerous sources, and challenges consumers and others to separate the facts from sensationalized…

Rett syndrome (RTT) is a rare monogenic disorder affecting 1 in 10,000 live female births causing severe neurodegenerative symptoms. We analyzed the molecular genetic variants in the gene encoding the methyl-CpG binding protein 2 ("MECP2") of 16 girls with RTT. Their mutation profile was as follows; Already described variants: p.R168X in…

The objective of this study was to assess the correlation of the Per3 gene VNTR polymorphism to insomnia patients in Bermuda. Buccal swabs were taken, and DNA was extracted, after which the genotypes of volunteers were characterised by using polymerase chain reaction. There were 25 total volunteers (21 females, 4 males, aged 20-79) that…

Water is one of the most common molecules in the universe. Water is polarized, but it has many states besides the normal tetrahedron depicted in standard biology texts. Water is also the most ubiquitous molecule on Earth, the universal solvent. It is the internal and external habitat of cells. Ecologically, water is contiguous with life and the…
