Variant summary
Our verdict is Likely pathogenic. Variant got 6 ACMG points: 6P and 0B. PM2PP3PP1PP4PS4_Supporting
This summary comes from the ClinGen Evidence Repository: The NM_000527.5(LDLR):c.299A>G (p.Asp100Gly) variant is classified as likely pathogenic for Familial Hypercholesterolemia by applying evidence codes PM2, PP1, PP3, PP4, PS4_supporting as defined by the ClinGen Familial Hypercholesterolemia Expert Panel LDLR-specific variant curation guidelines (https://doi.org/10.1016/j.gim.2021.09.012). The supporting evidence is as follows: - PM2: This variant is absent from gnomAD (gnomAD v2.1.1).- PP1: variant segregates with FH phenotype in 3 informative meiosis in 1 family from Laboratory of Genetics and Molecular Cardiology: 2 relatives with the phenotype and the variant and 1 relative without the phenotype and without the variant.- PP3: REVEL = 0.9.- PP4: Variant meets PM2 and is identified in at least 1 index case (1 index case from Laboratory of Genetics and Molecular Cardiology with Simon-Broome criteria of possible FH, 1 index case from PMID:11810272 clinically diagnosed with definite heterozygous FH), after alternative causes of high cholesterol were excluded.- PS4_supporting: Variant meets PM2 and is identified in 2 index cases (1 index case from Laboratory of Genetics and Molecular Cardiology with Simon-Broome criteria of possible FH, 1 index case from PMID:11810272 clinically diagnosed with definite heterozygous FH) LINK:https://erepo.genome.network/evrepo/ui/classification/CA10584833/MONDO:0007750/013
