Why the study?

Paediatric cardiomyopathy is a progressive, often lethal disorder and the most common cause of heart failure in children, but its genetic aetiology remains poorly characterised.

What is the genetic background of cardiomyopathy in Egyptian children using targeted next-generation sequencing?

Population

68 Egyptian children with cardiomyopathy (58 dilated and 10 left ventricular noncompaction cardiomyopathy)

Design

Hospital-based study

Discussion

Overview

Low detection rate with targeted NGS warrants caution in Egyptian children with cardiomyopathy; leaves open genome-wide testing for novel genes in consanguineous populations.

Structured PICO

What is the genetic background of cardiomyopathy in Egyptian children using targeted next-generation sequencing?

P
Population
68 Egyptian children with cardiomyopathy (58 idiopathic primary dilated cardiomyopathy and 10 left ventricular noncompaction cardiomyopathy)
I
Intervention
Targeted next-generation sequencing of cardiomyopathy-associated genes
O
Outcome
Detection of genetic variants associated with cardiomyopathysurrogate

Targeted next-generation sequencing yielded a low genetic detection rate (2.9%) in Egyptian children with cardiomyopathy, suggesting the need for genome-wide testing to identify novel genes in this highly consanguineous population.
