BACKGROUND: Laminopathies are rare diseases, whose cardiac manifestations are heterogeneous and, especially in their initial stage, similar to those of more common conditions, such as ischemic heart disease. Early diagnosis is essential, as these conditions can first manifest themselves with sudden cardiac death. Electrical complications usually appear before structural complications; therefore, it is important to take into consideration these rare genetic disorders for the differential diagnosis of brady and tachyarrhythmias, even when left ventricle systolic function is still preserved. CASE SUMMARY: A 60-year-old man, without history of previous disorders, presented in September 2019 to the emergency department because of the onset of syncope associated with hypotension. The patient was diagnosed with a high-grade atrioventricular block. A dual chamber pacemaker was implanted, but after the onset of a sustained ventricular tachycardia during physical exertion, a drug eluting stent was implanted on an intermediate stenosis on the left anterior descending artery, which had previously been considered non-haemodynamically significant. During the follow-up, the treating cardiologist, suspicious of the overall clinical picture, recommended a genetic test for the diagnosis of cardiomyopathies, which tested positive for a pathogenetic mutation of the lamin A/C gene. While awaiting the result of the genetic test and, later, the pacemaker to be upgraded to a biventricular defibrillator, a remote monitoring device was given to the patient in order to minimize in-person clinical evaluations during the coronavirus disease 2019-related lockdown. CONCLUSION: This case aims to raise awareness of the cardiological manifestations of laminopathies, which can be dangerously misdiagnosed as other, more common conditions.

Various next generation sequencing (NGS) based strategies have been successfully used in the recent past for tracing origins and understanding the evolution of infectious agents, investigating the spread and transmission chains of outbreaks, as well as facilitating the development of effective and rapid molecular diagnostic tests and contributing to the hunt for treatments and vaccines. The ongoing COVID-19 pandemic poses one of the greatest global threats in modern history and has already caused severe social and economic costs. The development of efficient and rapid sequencing methods to reconstruct the genomic sequence of SARS-CoV-2, the etiological agent of COVID-19, has been fundamental for the design of diagnostic molecular tests and to devise effective measures and strategies to mitigate the diffusion of the pandemic. Diverse approaches and sequencing methods can, as testified by the number of available sequences, be applied to SARS-CoV-2 genomes. However, each technology and sequencing approach has its own advantages and limitations. In the current review, we will provide a brief, but hopefully comprehensive, account of currently available platforms and methodological approaches for the sequencing of SARS-CoV-2 genomes. We also present an outline of current repositories and databases that provide access to SARS-CoV-2 genomic data and associated metadata. Finally, we offer general advice and guidelines for the appropriate sharing and deposition of SARS-CoV-2 data and metadata, and suggest that more efficient and standardized integration of current and future SARS-CoV-2-related data would greatly facilitate the struggle against this new pathogen. We hope that our 'vademecum' for the production and handling of SARS-CoV-2-related sequencing data, will contribute to this objective.
