One hundred and seventy\u2010three (0.41%) received a definite diagnosis of FH according to the Dutch Lipid Clinical Network Criteria\u2010Chinese Revised Version (DLCN\u2010CRV), and 18 patients subsequently agreed to undergo genetic testing. A next\u2010generation sequencing (NGS)\u2010based laboratory\u2010developed test covering the exonic regions of 24 lipid metabolism\u2010related genes was conducted alongside in silico analyses to identify possible FH mutations in 16 definite FH patients, according to the American College of Medical Genetics and Genomics (ACMG) criteria. Sanger sequencing was used to confirm mutations, and SWISS\u2010MODEL was used to simulate the molecular structures of the confirmed protein\u2010carrying mutations.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The FH prevalence was 0.41% for the 41,803 individuals (DLCN\u2010CRV grade\u2009&gt;8) and 25% of definite FH patients carried six FH pathogenic mutations (\u2265ACMG Class 4). All genetic variants were confirmed by Sanger sequencing. Five pathogenic variants on the LDLR gene (NM_000527: c.C1783T: p.R595W, c.T493G: p.W165G, c.G1879A: p.A627T, c.G682T: p.E228X, and exon10: c.G1432A: p.G478R) and one pathogenic variant on APOB (NM_000384: c.C10579T: p.R3527W) in 25% of the identified definite FH patients. Two pathogenic mutations, c.T493G (p.W165G) and c.C1783T (p.R595W), were added to the current genetic spectrum of FH in China.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>This study contributes to improving the current FH detection rate and genetic screening strategies;
