1. Genetics of COVID-19
Abstract Objective This narrative, non-systematic review provides an update on the genetic aspects of the SARS-CoV-2 virus and its interactions with the human genome within the context of COVID-19. Although the main focus is on the etiology of this new disease, the genetics of SARS-CoV-2 impacts prevention, diagnosis, prognosis, and the development of thera

3. The effect of mutation status, pathological features and tumor location on prognosis ın patients with colorectal cancer
SUMMARY OBJECTIVE: Colorectal cancer is the most common malignancy of the gastrointestinal tract. It is the third most common tumor in both genders and the second reason of cancer-related deaths. In recent years, tumor location has gained importance as a prognostic indicator. In this study, we aimed to analyze if there was a prognostic effect of tumor locat

4. Albinism: epidemiology, genetics, cutaneous characterization, psychosocial factors
Abstract Oculocutaneous albinism is an autosomal recessive disease caused by the complete absence or decrease of melanin biosynthesis in melanocytes. Due to the reduction or absence of melanin, albinos are highly susceptible to the harmful effects of ultraviolet radiation and are at increased risk of actinic damage and skin cancer. In Brazil, as in other par

6. IMPACT OF CURRENT DIET AT THE RISK OF NON-ALCOHOLIC FATTY LIVER DISEASE (NAFLD)
RESUMO A doença hepática gordurosa não alcoólica (DHGNA) afeta aproximadamente de 20% a 30% da população geral sendo prevalente entre os indivíduos obesos. Os fatores de risco associados à DHGNA são: doenças relacionadas à síndrome metabólica, fatores genéticos e meio ambiente. Nesta revisão, fornecemos uma compilação bibliográfica avaliand

7. Liaisons dangereuses: cross-border gene flow and dispersal of insecticide resistance-associated genes in the mosquito Aedes aegypti from Brazil and French Guiana
BACKGROUND In recent years, South America has suffered the burden of continuous high impact outbreaks of dengue, chikungunya and Zika. Aedes aegypti is the main mosquito vector of these arboviruses and its control is the only solution to reduce transmission. OBJECTIVES In order to improve vector control it is essential to study mosquito population geneti

8. The study of copy number variations in the regions of PRKAB2 and PPM1K among congenital heart defects patients
RESUMO OBJETIVO: Este estudo teve como objetivo avaliar a associação genética do número de cópias em dois genes (PRKAB2 e PPM1K) localizados em duas regiões (tetralogia de Fallot e comunicação interventricular) em uma população chinesa da etnia Han. METODOLOGIA: Um total de 200 pacientes com doença cardíaca congênita (100 pacientes com tetralo

9. Optimized protocol to isolate high quality genomic DNA from different tissues of a palm species
RESUMO A aplicação de técnicas moleculares para lidar com questões ecológicas e evolutivas requer DNA genômico de boa qualidade e quantidade. A qualidade do DNA isolado, no entanto, pode ser influenciada pelo tipo de tecido e pela maneira como a amostra foi conservada e manipulada. Portanto, personalizar protocolos para melhorar o isolamento do DNA e a

10. Genetic evidence of multiple reproductive strategies in a microendemic and threatened cactus (Cactaceae: Discocactus Pfeiff) in Bahia, Brazil
ABSTRACT Discocactus zehntneri subsp. petr-halfari, an endangered taxon, is represented by a single population in an anthropized area of Bahia, Brazil, where it is suffering due to extreme extractivism. Thus, information about this cactus, such as its reproductive patterns, is urgently needed to support conservation strategies. A population genetics approach

11. The chloroplast genome of the desiccation-tolerant moss Pseudocrossidium replicatum (Taylor) R.H. Zander
Abstract Mosses in conjunction with hornworts and liverworts are collectively referred to as bryophytes. These seedless, nonvascular plants are the closest extant relatives of early terrestrial plants and their study is essential to understand the evolutionary first steps of land plants. Here we report the complete chloroplast (cp) genome sequence of Pseudoc

12. Clinical research challenges in rare genetic diseases in Brazil
Abstract Rare diseases are defined as conditions with a prevalence of no more than 6.5 per 10,000 people. Although each rare disease individually affects a small number of people, collectively, the 6,000 to 8,000 rare conditions (80% of them with genetic cause) affect around 8% of the world’s population. Research about the natural history and underlying pa
