Description

In 2 unrelated families with idiopathic dilated cardiomyopathy (609909), Haghighi et al. (2003) identified a 116T-G transversion in the PLN gene, resulting in a leu39-to-ter (L39X) substitution that truncated the 52-amino acid protein in the highly conserved transmembrane domain II. The 2 homozygous individuals developed dilated cardiomyopathy and heart failure requiring cardiac transplantation at ages 16 and 27 years, respectively; 11 heterozygous individuals exhibited variable clinical findings indicating incomplete penetrance of the cardiomyopathy phenotype: 2 had dilated cardiomyopathy with ejection fractions of 25% or less, 4 had left ventricular hypertrophy with normal left ventricular systolic function, and 5 had normal echocardiograms.

In a 65-year-old Australian woman who was diagnosed with familial hypertrophic cardiomyopathy (CMH18; 613874) at age 61 years, Chiu et al. (2007) identified heterozygosity for the L39X mutation in the PLN gene. Echocardiography revealed asymmetric septal hypertrophy with a maximum wall thickness of 20 mm, normal systolic contractile function, and no evidence of left ventricular dilation. Her mother had also been diagnosed with CMH and had died at age 80 of noncardiac causes.

In a 58-year-old man with CMH18, Landstrom et al. (2011) identified heterozygosity for the L39X mutation in the PLN gene. The mutation segregated with disease in the family and was not found in 300 controls.
