Avaliação de painel multigenes em mulheres brasileiras com câncer de mama

Introdução: Apenas 5-10% dos casos de câncer de mama estão relacionados a variantes genéticas herdadas e mutações nos genes BRCA1 e BRCA2, relacionadas à Síndrome do câncer de mama e ovário hereditário (SMOH), são identificadas na maioria desses casos. Além dos genes BRCA1 e BRCA2, outros g...

Implicaciones éticas de la identificación del potencial atlético infantil mediante pruebas genéticas
Ethical implications of the identification of children´s athletic potential through genetic testing

Introducción: La irrupción de la investigación genética en la esfera del deporte ha permitido la localización en el genoma de un considerable número de genes implicados en el rendimiento deportivo y, con ello, el desarrollo de tecnologías genéticas orientadas a la identificación del potencial at...

Obsessive-compulsive disorder in a patient with SCA type 1

Rev. bras. neurol; 55 (4), 2019
For many years, the cerebellum was thought to be only responsible for balance, movement, planning and execution. Nowadays, it is well accepted that most cerebellar connections are involved in non-motor functions. Herein, we provide a case report in which a 27-year-old Brazilian male, diagnosed with Obses...

The USPSTF recommends the use of family risk assessment tools in primary care for cancer related to BRCA gene mutations 1/2

Validation of ROPScore to predict retinopathy of prematurity among very low birth weight preterm infants in a southern Brazilian population

Arq. bras. oftalmol; 82 (6), 2019
ABSTRACT Purposes: To evaluate the sensitivity, specificity, and cutoff points for the ROPScore, which is based on cumulative risk factors for the prediction of retinopathy of prematurity (ROP), in a population of very low birth weight (BW) preterm infants in southern Brazil. Methods: The medical recor...

How diseases became "genetic"

Abstract This article examines the origins of the term "genetic disease." In the late 19 and early 20th century, an earlier idea that diseases that occur in families reflect a vague familiar "predisposition" was replaced by the view that such diseases have specific causes, while Mendelian genetics provid...

Pheochromocytoma and paraganglioma: implications of germline mutation investigation for treatment, screening, and surveillance

ABSTRACT Objective Paraganglioma (PGL) and pheochromocytoma (PCC) are rare neuroendocrine tumors that were considered to be predominantly sporadic. However, with the identification of novel susceptibility genes over the last decade, it is currently estimated that up to 40% of cases can occur in the con...

Basic and clinical insights in catecholaminergic (familial) polymorphic ventricular tachycardia

Rev. invest. clín; 71 (4), 2019
Abstract Catecholaminergic polymorphic ventricular tachycardia (CPVT) is a potentially lethal disease, whose characteristic ventricular tachycardias are adrenergic-dependent. Although rare, CPVT should be considered in the differential diagnosis of young individuals with exercise-induced syncope. Mutatio...

Importance of Genetic Testing in Dilated Cardiomyopathy: Applications and Challenges in Clinical Practice

Arq. bras. cardiol; 113 (2), 2019
Abstract Dilated cardiomyopathy (DCM) is a clinical syndrome characterized by left ventricular dilatation and contractile dysfunction. It is the most common cause of heart failure in young adults. The advent of next-generation sequencing has contributed to the discovery of a large amount of genomic data ...
