I
Intervention
Whole exome sequencing and clinical profiling
O
Outcome
Clinical, functional, and genetic profiles including molecular yield and key gene variants
Pediatric cardiomyopathies in India show distinct genetic architectures and molecular yields across subtypes, with specific sarcomeric mutations correlating with severe clinical presentations.
