MiRNA-Mediated Epigenetic Mechanisms
This entry discuss the role of ncRNAs as mediators of epigenetic pathways associated with carcinogenesis, and provides an overview on how deregulated microRNAs (miRNAs) and long non-coding RNAs (lncRNAs) alter the expression of cancer-promoting genes.  Overall, miss regulated expression of ncRNAs alter cell cycle progression and apoptosis to increase proliferation, thereby facilitating cellular transformation into malignancies. The potential for using ncRNAs as targets for early prognosis and for developing cancer therapies is discussed.

Inheriting Genetic Conditions
It is not always easy to determine whether a condition in a family is inherited. A genetics professional can use a person's family history (a record of health information about a person's immediate and extended family) to help determine whether a disorder has a genetic component.

Type 1 Diabetes
Type 1 diabetes is a disorder characterized by abnormally high blood sugar levels. In this form of diabetes, specialized cells in the pancreas called beta cells stop producing insulin. Insulin controls how much glucose (a type of sugar) is passed from the blood into cells for conversion to energy. Lack of insulin results in the inability to use glucose for energy or to control the amount of sugar in the blood.

Human Diseases with Mutations in the BRPF1-KAT6A/KAT6B Complex
The bromodomain and PHD finger–containing protein1 (BRPF1) is a member of family IV of the bromodomain-containing proteins that participate in the post-translational modification of histones. Patients with BRPF1 mutations often display intellectual disability or suffer from leukemia or medulloblastoma. BRPF1 is an activator and a scaffold protein of a multiunit complex, with other members being KAT6A/KAT6B, the inhibitor of growth 5 (ING5) or ING4 and MYST/Esa1-associated factor 6 (MEAF6).

15q13.3 Microdeletion
15q13.3 microdeletion is a chromosomal change in which a small piece of chromosome 15 is deleted in each cell. The deletion occurs on the long (q) arm of the chromosome at a position designated q13.3. This chromosomal change increases the risk of intellectual disability, seizures, behavioral problems, and psychiatric disorders. However, some people with a 15q13.3 microdeletion do not appear to have any associated features.

Functions of snoRNAs
Small nucleolar RNAs (snoRNAs) constitute a class of intron-derived non-coding RNAs ranging from 60 to 300 nucleotides. snoRNAs canonically localize in the nucleolus where they play pivotal roles in pre-ribosomal RNA processing, guiding RNA modifications. Based on the type of modification they facilitate, namely methylation or pseudouridylation, they are classified into two main families—box C/D and box H/ACA snoRNAs. Investigations have revealed the unconventional synthesis and biogenesis strategies of snoRNAs, indicating more profound roles in pathogenesis than previously envisioned.

Diet: DNA Methylation and Cancer
Cancer initiation and progression is an accumulation of genetic and epigenetic modifications. DNA methylation is a common epigenetic modification that regulates gene expression, and aberrant DNA methylation patterns are considered a hallmark of cancer. The human diet is a source of micronutrients, bioactive molecules, and mycotoxins that have the ability to alter DNA methylation patterns and are thus a contributing factor for both the prevention and onset of cancer. In this review, we summarize the literature on dietary micronutrients, bioactive compounds, and food-borne mycotoxins that affect DNA methylation patterns and identify their potential in the onset and treatment of cancer.

Multiple Familial Trichoepithelioma
Multiple familial trichoepithelioma is a condition involving multiple skin tumors that develop from structures associated with the skin (skin appendages), such as hair follicles and sweat glands. People with multiple familial trichoepithelioma typically develop large numbers of smooth, round tumors called trichoepitheliomas, which arise from hair follicles. Trichoepitheliomas are generally noncancerous (benign) but occasionally develop into a type of skin cancer called basal cell carcinoma.

CRISPR-Based Technologies in Yeasts
CRISPR, a family of DNA sequences found in the genomes of bacteria and archaea. Compared with traditional genetic engineering methods and other gene-editing alternatives, CRISPR/Cas9 is described as efficient, easy-to-use, and able to target multiple sites, besides being “nature-made,” as bacteria have been using it for millions of years. CRISPR is being tested in vineyards and wineries to target some of wine’s biggest challenges. Therefore, CRISPR opens brand new doors for winemakers using commercial yeasts when it comes to efficiently produce target flavors and reducing harmful compounds and off-odors.

Immune Mediated Diseases
Immune-mediated diseases (IMDs) are complex pathologies that are strongly influenced by environmental and genetic factors. Associations between genetic loci and susceptibility to these diseases have been widely studied, and hundreds of risk variants have emerged during the last two decades, with researchers observing a shared genetic pattern among them.

ALS-Specific GWAS Challenges
Amyotrophic Lateral Sclerosis (ALS) is the most common late-onset motor neuron disorder, but our current knowledge of the molecular mechanisms and pathways underlying this disease remains elusive. Genome-Wide Association Studies (GWAS) aim to identify Single Nucleotide Polymorphisms (SNPs) and other types of genetic variation that are more frequent in patients than in people without the disease, using a variety of statistical tests. Despite the rapid recent technological advances and great efforts in the GWAS field that have led to the genomic profiling of large ALS cohorts, the identified associations have been able to explain only a very small fraction of the ALS heritability and aetiology. Here, we outline ALS-Specific GWAS Challenges, explaining the limitations of traditional GWAS analyses, considering known features of the ALS genetic architecture and hypotheses about ALS pathology (e.g., multilocus interactions, rare variations with low effect size). Future advances in the genomic and machine learning fields may bring about a better understanding of ALS genetic architecture and enable improved personalized approaches to this and other devastating and complex diseases.
