Teaching and training of human resources for genetics and genomics in Brazil.

This manuscript reviewed the state of the art about the teaching and training of human resources for genetics and genomics in Brazil. We presented the national scenario of teaching genetics in medical undergraduate and other health courses. We discussed the training of medical geneticists through medical residency and addressed the training in genetics of physicians from specialties other than genetics.

Investigating the correlation between genotype and phenotype in Prader-Willi syndrome: a study of 45 cases from Brazil.

Background: Prader-Willi syndrome (PWS) is a genetic disorder characterized by abnormalities in the 15q11-q13 region. Understanding the correlation between genotype and phenotype in PWS is crucial for improved genetic counseling and prognosis. In this study, we aimed to investigate the correlation between genotype and phenotype in 45 PWS patients who previously underwent methylation-sensitive high-resolution melting (MS-HRM) for diagnosis.

New and Known Variants in a Series of Latin American Patients with Holoprosencephaly.

Holoprosencephaly (HPE) is the failure of the embryonic forebrain to develop into 2 hemispheres promoting midline cerebral and facial defects. The wide phenotypic variability and causal heterogeneity make genetic counseling difficult. Heterozygous variants with incomplete penetrance and variable expressivity in the , , , and genes explain ∼25% of the known causes of nonchromosomal HPE.

Conceptions on genetics in a group of college students.

The purpose of this study was to investigate awareness, beliefs, and opinions on genetics in a group of Brazilian college students from several courses. The study used the focus group technique with the participation of 19 students, divided into four groups. Also, it used the isotopic reading technique to analyze the material.

A survey on inborn errors of metabolism in 323 neonates from the state of Rio de Janeiro, Brazil.

Inborn errors of metabolism (IEM) are a relevant cause of morbidity and death among children, and neonates in particular. However, little is known about the prevalence of these disorders in Brazilian newborns. Our laboratory of IEM (LABEIM) at the Department of Biochemistry, Institute of Chemistry, Federal University of Rio de Janeiro (UFRJ), has been working on the diagnosis of IEM since 1988.
