GET3 and cardiomyopathy: Targeted next-generation sequencing of 48 genes implicated in cardiomyopathy revealed no potentially deleterious variants.18 Exome sequencing in the affected proband (II:2) and her healthy parents identified 3 novel heterozygous variants in ASNA1 (NM_004317.2): 2 variants c.867C>G p.(Cys289Trp) and c.913C>T p.(Gln305*) in cis configuration on the paternal allele, and a missense variant c.488T>C p.(Val163Ala) on the maternal allele (Figure 1A and 1B).
