High match ARRHYTHMOGENIC RIGHT VENTRICULAR DYSPLASIA, FAMILIAL, 1; ARVD1

Arrhythmogenic right ventricular dysplasia (ARVD) is a clinical and pathologic entity for which the diagnosis rests on electrocardiographic and angiographic criteria; pathologic findings, replacement of ventricular myocardium with fatty and fibrous elements, preferentially involve the right ventricular free wall. It is inherited in an autosomal dominant manner with reduced penetrance and is one of the major genetic causes of juvenile sudden death. When the dysplasia is extensive, it may represent the Uhl anomaly ('parchment right ventricle'). The presenting finding is usually recurrent, sustained ventricular tachycardia with left bundle branch block configuration. Basso et al. (2009) provided a detailed review of ARVD, including diagnosis, pathogenesis, treatment options, and genetics. Genetic Heterogeneity of Familial Arrhythmogenic Right Ventricular DysplasiaOther forms of ARVD include ARVD2 (OMIM ), caused by mutation in the RYR2 gene (OMIM ) on chromosome 1q42-q43; ARVD3 (OMIM ), on chromosome 14q12-q22; ARVD4 (OMIM ), on chromosome 2q32.1-q32.3; ARVD5 (OMIM ), caused by mutation in the TMEM43 gene (OMIM ) on chromosome 3p23; ARVD6 (OMIM ), on chromosome 10p14-p12; ARVD8 (OMIM ), caused by mutation in the DSP gene (OMIM ) on chromosome 6p24; ARVD9 (OMIM ), caused by mutation in the PKP2 gene (OMIM ) on chromosome 12p11; ARVD10 (OMIM ), caused by mutation in the DSG2 (OMIM ) on chromosome 18q12.1; ARVD11 (OMIM ), caused by mutation in the DSC2 gene (OMIM ) on chromosome 18q12.1; ARVD12 (OMIM ), caused by mutation in the JUP gene (OMIM ) on chromosome 17q21; and ARVD13 (OMIM ), caused by mutation in the CTNNA3 gene (OMIM ) on chromosome 10q21.ARVD7 is a former designation for a form of myopathy and ARVD mapped to chromosome 10q22, which was later found to be a form of myofibrillar myopathy (MFM1 ) caused by mutation in the DES gene (OMIM ) on chromosome 2q35.Christensen et al. (2010) screened 65 ARVD probands for mutations in 5 desmosomal genes as well as the TGFB3 gene (OMIM ), and identified 19 different mutations in the desmosomal genes in 12 of the families, including 7 with more than 1 mutation. In 6 families, digenic mutation carriers were identified, with at least 1 of the mutations being absent in the control population. The authors stated that their findings partially supported a gene dosage effect, although phenotypic variation was large.Nitoiu et al. (2014) reviewed desmosome biology in cardiocutaneous syndromes and inherited skin disease, including discussion of the involvement of the DSP, PKP2, DSG2, DSC2, and JUP genes.

High match DESMINOPATHY

Desminopathy is a rare genetic skeletal muscle disease characterized by abnormal chimeric aggregates of desmin and other cytoskeletal proteins and granulofilamentous material at the ultrastructural level in muscle biopsies and variable clinical/ myopathological features, age of disease onset and rate of disease progression. Patients present with bilateral skeletal muscle weakness that starts in distal leg muscles and spreads proximally, sometimes involving trunk, neck flexors and facial muscles and often cardiomyopathy manifested by conduction blocks, arrhythmias, chronic heart failure, and sometimes tachyarrhythmia. Weakness eventually leads to wheelchair dependence. Respiratory insufficiency can be a major cause of disability and death, beginning with nocturnal hyperventilation with oxygen desaturation and progressing to daytime respiratory failure.

High match FAMILIAL DILATED CARDIOMYOPATHY WITH CONDUCTION DEFECT DUE TO LMNA MUTATION

Familial dilated cardiomyopathy with conduction defect due to LMNA mutation is a rare familial dilated cardiomyopathy characterized by left ventricular enlargement and/or reduced systolic function preceded or accompanied by significant conduction system disease and/or arrhythmias including bradyarrhythmias, supraventricular or ventricular arrhythmias. Disease onset is usually in early to mid-adulthood. Sudden cardiac death may occur and may be the presenting symptom. In some cases, it is associated with skeletal myopathy and elevated serum creatine kinase.

Autosomal dominant limb-girdle muscular dystrophy type 1B (LGMD1B) is a subtype of autosomal dominant limb girdle muscular dystrophy characterized by a variable age of onset of progressive shoulder and hip girdle weakness, with inferior limbs usually being affected prior to upper limbs, and mild joint contractures. LGMD1B is also associated with cardiac dysrhythmias, including atrioventricular conduction blocks, and late-onset dilated cardiomyopathy, that may lead to sudden death.
