Multinational experience with next-generation sequencing: opportunity to identify transthyretin cardiac amyloidosis and Fabry disease.

Background: Sarcomeric hypertrophic cardiomyopathy (HCM) must be differentiated from phenotypically similar conditions because clinical management and prognosis may greatly differ. Patients with unexplained left ventricular hypertrophy require an early, confirmed genetic diagnosis through diagnostic or predictive genetic testing. We tested the feasibility and practicality of the application of a 17-gene next-generation sequencing (NGS) panel to detect the most common genetic causes of HCM and HCM phenocopies, including treatable phenocopies, and report detection rates.

[Congenital adrenal hyperplasia newborn screening: Rio de Janeiro experience].

Objective: To determine the 17OH progesterone (17OHP) levels in the neonatal screening for Congenital Adrenal Hyperplasia due to 21 hydroxylase deficiency (CAH-21OHD).

Casuistic And Method: The evaluation was performed using 76,360 paper filter samples, obtained from newborn screening in Rio de Janeiro from June 1992 to December 2000. The 17OHP were assayed by fluoroimmunoassay method using the blood collected onto filter paper cards.
