Mycobacterium tuberculosis and HIV-1: Evolution
This entry reviews the genetic evolution and adaptation to the host environment of M. tuberculosis and HIV-1. It provides an overview of the latest developments in the knowledge about the genetic diversity of these devastating intracellular human pathogens and its impact on the host immune system, virulence, drug resistance propensity and other relevant aspects. We also proposed a novel topic in the literature regarding the use of single cell "omics" to study the interacting evolutionary dynamics of M. tuberculosis and HIV-1 in co-infection, at the cellular niche of monocytes/macrophages.

Channelopathy Genes in Pulmonary Arterial Hypertension
Pulmonary arterial hypertension (PAH) is a rare, progressive vasculopathy with significant cardiopulmonary morbidity and mortality. Roles for rare variants in three channelopathy genes—ABCC8, ATP13A3, and KCNK3—have been validated in multiple PAH cohorts, and in aggregate explain ~2.7% of PAH cases. Complete or partial loss of function has been demonstrated for PAH-associated variants in ABCC8 and KCNK3. Channels can be excellent targets for drugs, and knowledge of mechanisms for channel mutations may provide an opportunity for the development of PAH biomarkers and novel therapeutics for patients with hereditary PAH but also potentially more broadly for all patients with PAH.

Spinal and Bulbar Muscular Atrophy
Spinal and bulbar muscular atrophy, also known as Kennedy disease, is a disorder of specialized nerve cells that control muscle movement (motor neurons). These nerve cells originate in the spinal cord and the part of the brain that is connected to the spinal cord (the brainstem).

Dissecting Polygenic Etiology of Ischemic Stroke
Ischemic stroke (IS), the leading cause of death and disability worldwide, is caused by many modifiable and non-modifiable risk factors. This complex disease is also known for its multiple etiologies with moderate heritability. Polygenic risk scores (PRSs), which have been used to establish a common genetic basis for IS, may contribute to IS risk stratification for disease/outcome prediction and personalized management. Statistical modeling and machine learning algorithms have contributed significantly to this field. For instance, multiple algorithms have been successfully applied to PRS construction and integration of genetic and non-genetic features for outcome prediction to aid in risk stratification for personalized management and prevention measures. PRS derived from variants with effect size estimated based on the summary statistics of a specific subtype shows a stronger association with the matched subtype. The disruption of the extracellular matrix and amyloidosis account for the pathogenesis of cerebral small vessel disease (CSVD). Pathway-specific PRS analyses confirm known and identify novel etiologies related to IS.

Factors to Improve Healthy Reproduction
Humans’ health is the result of a complex and balanced interplay between genetic factors, environmental stimuli, lifestyle habits, and the microbiota composition. The knowledge about their single contributions, as well as the complex network linking each to the others, is pivotal to understand the mechanisms underlying the onset of many diseases and can provide key information for their prevention, diagnosis and therapy. This applies also to reproduction. Reproduction, involving almost 10% of our genetic code, is one of the most critical human’s functions and is a key element to assess the well-being of a population. The last decades revealed a progressive decline of reproductive outcomes worldwide. As a consequence, there is a growing interest in unveiling the role of the different factors involved in human reproduction and great efforts have been carried out to improve its outcomes. As for many other diseases, it is now clear that the interplay between the underlying genetics, our commensal microbiome, the lifestyle habits and the environment we live in can either exacerbate the outcome or mitigate the adverse effects.

Symptomatic Heterozygosity
As a rule of thumb, heterozygous carriers of variants associated with recessive diseases are asymptomatic. This can be confirmed by large population genetic studies and the asymptomatic status of heterozygous family members in segregation analyses. Symptomatic heterozygotes, defined as symptomatic carriers of a recessive autosomal disease, are individuals carrying only one copy of the pathogenic/likely pathogenic variant in biallelic autosomal Mendelian diseases. Considering the available literature, a symptomatic heterozygous status in autosomal diseases is extremely rare and has been based on case reports only, although some large studies have suggested an increased risk for some diseases among heterozygotes. Also, individuals who carry just one variant of the disease-causing gene and who display quite a severe phenotype are often not defined as symptomatic carriers per se; rather, they are classified as an example of a dominant inheritance with a milder disease form. Indeed, sometimes only a fine line exists between these two conditions. In addition, recent population studies investigating links between genetic variants and quantitative traits have shown a spectrum of subclinical phenotypes associated with heterozygosity in some disease variants. A broad range of intermediate subclinical phenotypes has suggested significant heterozygous phenotypic effects in some Mendelian biallelic diseases.
