YES
Clinical data, including genetic testing results and lipid profiles, of pediatric patients with confirmed or suspected familial hypercholesterolemia will be prospectively collected and followed as part of a registry study.
Others
We will establish a registry targeting patients and children identified with elevated low-density lipoprotein cholesterol (LDL-C) through the Kagawa Prefecture pediatric lifestyle disease prevention screening program and other health checkups, as well as their family members, who are diagnosed with or suspected of having familial hypercholesterolemia (FH). This registry will longitudinally collect and accumulate disease-related data, with the aim of contributing to the generation of evidence derived from early treatment in pediatric FH patients and from the prompt diagnosis and treatment of affected family members.

Male and Female
Among patients and children identified with elevated LDL-C through the Kagawa Prefecture pediatric lifestyle disease prevention screening program and other health checkups, as well as their family members, those who are diagnosed with or suspected of having familial hypercholesterolemia (FH) according to the most recent diagnostic criteria of the Japanese Atherosclerosis Society (JAS) guidelines for FH or pediatric FH will be evaluated. The fulfillment of the latest guideline criteria will be confirmed through interviews with the patients or children, or directly with their family members, as well as through clinical examination.
Patients and children diagnosed with hyper LDL cholesterolemia other than familial hypercholesterolemia (FH), including secondary causes of elevated LDL-C, will be excluded. The diagnosis of secondary hyper LDL cholesterolemia will be based on the identification of underlying conditions such as diabetes mellitus, hypothyroidism, nephrotic syndrome, and cholestatic liver disease or medication-related causes (e.g., corticosteroids), assessed through blood tests and medication history.

Familial hypercholesterolemia (FH) is an autosomal dominant disorder mainly caused by mutations in LDL receptor-related genes. Patients with FH have markedly elevated LDL cholesterol (LDL-C) levels from birth. If untreated, FH is associated with premature coronary artery disease and reduced life expectancy. Heterozygous FH affects approximately 1 in 300 individuals. Because atherosclerosis may progress from childhood and its progression can be slowed by treatment, early diagnosis and treatment of pediatric FH are important.
In Kagawa Prefecture, a pediatric lifestyle disease prevention screening program is conducted throughout the prefecture. Every year, all fourth-grade elementary school students, about 8,000 children, undergo blood testing including LDL-C measurement, with a participation rate of over 90%. This has established a prefecture-wide universal pediatric lipid screening system, which is unique in Japan and provides a valuable opportunity to accumulate large-scale data.
In this study, we will longitudinally follow children suspected of having FH through this screening program and other health checkups, as well as their family members, and establish a registry. This registry may contribute to better treatment strategies for pediatric FH, earlier diagnosis of affected family members, risk prediction in children based on parental clinical features, early personalized medicine, and the development of a regional support system involving local governments, medical associations, and core hospitals.
