This study aims to understand the state of onset of NLSD(neutral lipid storage disease) / TGCV(triglyceride deposit cardiovasculopathy) worldwide, background information of affected patients, and natural history of the disease, as well as exploring the prognostic factors and assessing the efficacy of disease-specific treatment.
Since NLSD is a rare disease, its clinical manifestation and clinical course have not been sufficiently clarified. Also, the number of patients in each country is limited. As such, it is considered difficult to fully investigate this disease without international collaboration. Therefore, we have established the International Registry of NLSD / TGCV. Also, all patients with Jordans' anomaly of peripheral polymorphonuclear leukocytes are established as the subjects of entry when starting the registry, to allow entry of patients with NLSD due to genes other than mutations of ATGL and CGI-58 genes.
Time Perspective:This study is both Prospective (registering patients who are diagnosed with NLSD / TGCV) and Retrospective (registering only the medical record of previous patients).
Patients who are diagnosed with NLSD /TGCV (including adults only)
Exclusion Criteria:
Patients who are diagnosed with NLSD / TGCV
Period from the diagnosis of NLSD / TGCV to death from any cause
This is the period from the date of diagnosis of NLSD / TGCV to the date of death from any cause. The last date of confirmation of survival will be used as the cut-off date for living patients and patients who are lost to follow-up.
