A novel LAMP2 mutation associated with severe cardiac hypertrophy and microvascular remodeling in a female with Danon disease: a case report and literature review. Cardiovasc Pathol 2016; 25:423-31.

Abstract
BACKGROUND Danon disease (DD) is a rare disorder characterized by cardiomyopathy, intellectual disability, and proximal myopathy. It is caused by mutations in the LAMP2 gene on X chromosome. Female patients most often present with late-onset cardiomyopathy and slow disease progression, but early-onset cases with unfavorable prognosis have been reported. CASE REPORT We describe the clinical, pathological, and molecular features of a novel LAMP2 c.453delT mutation in a female patient with severe hypertrophic cardiomyopathy, Wolff Parkinson White (WPW) syndrome and rapid progression to heart failure, requiring heart transplant. Immunohistochemical analysis of LAMP2 in the explanted heart revealed a mosaic pattern of distribution, with discrete clusters of either stained or unstained cardiac myocytes, the latter being more frequent in the septum. These findings paralleled X chromosome inactivation within the myocardium. Interestingly, multiple foci of microscarring were found on histology in the Left Ventricle (LV) free wall and septum, in a close spatial relationship with remodeling and severe stenosis of intramural coronary arterioles. CONCLUSIONS Our findings suggest that several features may contribute to the early and severe cardiac phenotype in female DD patients. The type of mutation may account for the early disease onset, while both the inhomogeneous distribution of LAMP2 loss and the presence of microvascular remodeling may be determinant in the rapid progression to heart failure.

Protein degradation in a LAMP-2-deficient B-lymphoblastoid cell line from a patient with Danon disease. Biochim Biophys Acta Mol Basis Dis 2016; 1862:1423-32.

Abstract
Danon disease, a condition characterized by cardiomyopathy, myopathy, and intellectual disability, is caused by mutations in the LAMP-2 gene. Lamp-2A protein, generated by alternative splicing from the Lamp-2 pre-mRNA, is reported to be the lysosomal membrane receptor essential for the chaperone-mediated autophagic pathway (CMA) aimed to selective protein targeting and translocation into the lysosomal lumen for degradation. To study the relevance of Lamp-2 in protein degradation, a lymphoblastoid cell line was obtained by EBV transformation of B-cells from a Danon patient. The derived cell line showed no significant expression of Lamp-2 protein. The steady-state mRNA and protein levels of alpha-synuclein, IΚBα, Rcan1, and glyceraldehyde-3-phosphate dehydrogenase, four proteins reported to be selective substrates of the CMA pathway, were similar in control and Lamp-2-deficient cells. Inhibition of protein synthesis showed that the half-life of alpha-synuclein, IΚBα, and Rcan1 was similar in control and Lamp-2-deficient cells, and its degradation prevented by proteasome inhibitors. Both in control and Lamp-2-deficient cells, induction of CMA and macroautophagy by serum and aminoacid starvation of cells for 8h produced a similar decrease in IΚBα and Rcan1 protein levels and was prevented by the addition of lysosome and autophagy inhibitors. In conclusion, the results presented here showed that Lamp-2 deficiency in human lymphoblastoid cells did not modify the steady-state levels or the degradation of several protein substrates reported as selective substrates of the CMA pathway.

Abstract
Danon disease is a rare X-linked dominant lysosomal disease due to the primary deficiency of lysosome-associated membrane protein 2 (LAMP2) gene. Cardiomyopathy, skeletal myopathy and mental retardation are the typical triad of Danon disease. More than 60 LAMP2 mutations have been reported. The molecular mechanism is defects in LAMP2 protein (due to LAMP2 mutation) which causes insidious glycogen accumulation in cardiac muscle cells and resulting in cardiac hypertrophy and electrophysiological abnormalities. However, there are significant differences between the male and female Danon disease patients with regard to clinical features and cardiac manifestations. The clinical symptoms are variable, from asymptomatic to sudden cardiac death. Wolff-Parkinson-White syndrome is more common in male than female patients. Hypertrophic cardiomyopathy is predominant in male patients, whereas the similar prevalence of hypertrophic and dilated cardiomyopathy in female patients. Male patients are diagnosed usually at teenage, whereas the diagnosis and events occurred approximately 15 years later in female than male patients. Heart transplantation is the reliable treatment once the occurrence of heart failure and should be considered as early as possible due to its rapid progression.

Abstract
Danon disease is a rare lysosomal disorder. It is due to deficiency of lysosomal-associated protein-2. In human LAMP-2 gene is located at chromosome region Xq24. Danon disease is characterized by hypertrophic cardiomyopathy, skeletal myopathy, mental retardation and retinopathy. To date, the morphological characterization of Danon disease has been limited to endomyocardial and skeletal muscle biopsies. In the current study we demonstrated that electron microscopy of a more accessible tissue, skin biopsies, is a useful method in the diagnosis of Danon disease.

Abstract
Danon disease is caused by deficiency of lysosome-associated membrane protein-2 (LAMP-2). It is characterized clinically by cardiomyopathy, myopathy, and mental retardation in boys. Herein we report a 13-year-old female patient with Danon disease who presented with early-onset skeletal myopathy and cardiomyopathy. She had a de novo novel mutation in the LAMP2 gene, and her muscles showed many autophagic vacuoles with sarcolemmal features and complete absence of LAMP-2 expression. To the best of our knowledge, this girl is one of the earliest-onset manifesting carriers of Danon disease with typical muscle pathology.

Abstract
BACKGROUND Danon disease is an X-linked dominant disorder characterized by the clinical triad of hypertrophic cardiomyopathy, skeletal myopathy, and variable mental retardation. Pathologically, autophagic vacuoles are noted in both skeletal and cardiac muscle. It exhibits an X-linked dominant mode of inheritance, and male carriers are severely affected, whereas female carriers develop milder and later-onset cardiac symptoms. Danon disease has been associated with mutations in the lysosome-associated membrane glycoprotein 2 (LAMP2) gene located at Xq24, typically resulting in splicing defects or protein truncation affecting the LAMP2. Because of its rarity, the full spectrum of genetic mutation resulting in Danon disease has not been elucidated. METHODS AND RESULTS We analyzed 3 male cases with clinical and pathological findings consistent with Danon disease. Comprehensive mutational analysis failed to yield detectable products for selected LAMP2 exons, and genomic DNA deletion was suspected. Genomic junction fragment polymerase chain reaction analysis in case 1 identified a novel Alu-mediated 34-kb microdeletion encompassing the entire 5'-untranslated region and exon 1 of LAMP2. In case 2 and 3, junctional polymerase chain reaction and Southern blot analyses mapped the breakpoint to an MIRb and (TA)(n) simple repeats present in intron 3, which determined a 64-kb and a 58-kb deletion, respectively, thereby ablating exons 4 to 10. Western blot analysis confirmed the absence of LAMP2 in protein extract from lymphocytes of index case 2. CONCLUSIONS This article is the first report of Danon disease caused by microdeletions at Xq24, which functionally ablate LAMP2. The microdeletion mechanism appears to involve 1 Alu-mediated unequal recombination and 2 chromosomal breakage points involving TA-rich repeat sequences.

Abstract
Two families of Greek patients with subclinical to severe cardiomyopathy are presented. The diagnosis of Danon disease was supported by a total lack of LAMP2 immunostaining in cultured skin fibroblasts and muscle biopsies. The LAMP2 mutation carried by one patient (c.928G>A) has already been reported but with different symptoms. The second patient had a novel point deletion. This has not been described previously, but it could be detected easily by restriction analysis. This mutation was also found in the patient's brother, and it was associated with severe cardiomyopathy leading to heart failure. Surprisingly, the proband also had partial reduction of alpha-galactosidase A activity, despite the absence of characteristic clinical features of Fabry disease. A substitution in the GLA gene (c.937G>T) was found, and its involvement in the cardiac disease is discussed.
