Hemi- and Homozygous Loss-of-Function Mutations in DSG2 (Desmoglein-2) Cause Recessive Arrhythmogenic Cardiomyopathy with an Early Onset.

About 50% of patients with arrhythmogenic cardiomyopathy (ACM) carry a pathogenic or likely pathogenic mutation in the desmosomal genes. However, there is a significant number of patients without positive familial anamnesis. Therefore, the molecular reasons for ACM in these patients are frequently unknown and a genetic contribution might be underestimated.

[Familial left ventricular noncompaction: phenotypes and clinical course. Results of the multicenter registry].

Aim: To analyze and demonstrate various phenotypes in patients with familial left ventricular noncompaction (LVNC).

Materials And Methods: In 2013 was created a multicenter registry of LVNC patients. On its basis 30 families with a familial LVNC were selected.

The Desmin () Mutation p.A337P Is Associated with Left-Ventricular Non-Compaction Cardiomyopathy.

Here, we present a small Russian family, where the index patient received a diagnosis of left-ventricular non-compaction cardiomyopathy (LVNC) in combination with a skeletal myopathy. Clinical follow-up analysis revealed a LVNC phenotype also in her son. Therefore, we applied a broad next-generation sequencing gene panel approach for the identification of the underlying mutation.
