Morphologic and clinical aspects of Danon disease in a patient with a mutation c.137G > A in the LAMP-2 gene.

Abstract excerpt

BACKGROUND: Danon disease is caused by a primary deficiency of lysosome-associated membrane protein-2 (LAMP-2). MATERIALS AND METHODS: Our study describes a 19-year-old man with isolated hypertrophic cardiomyopathy, in whom we performed DNA analysis and compared results of microscopic analysis of skeletal and cardiac muscles. RESULTS: Sequencing of the LAMP-2 gene revealed a novel point mutation c.137G > A in...
