Variant summary
Our verdict is Uncertain significance. Variant got 1 ACMG points: 2P and 1B. BP4PM2
This summary comes from the ClinGen Evidence Repository: The NM_000527.5(LDLR):c.240C>A (p.Asn80Lys)variant is classified as Uncertain significance - insufficient evidence for Familial Hypercholesterolemia by applying evidence code PM2, BP4 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) BP4 - REVEL = 0.389. It is below 0.50. splicing evaluation required. Functional data not availableA) not on limitsB) does not create AG or GTVariant is not predicted to alter splicing LINK:https://erepo.genome.network/evrepo/ui/classification/CA10584802/MONDO:0007750/013

Uncertain significance, criteria provided, single submitter | clinical testing | All of Us Research Program, National Institutes of Health | Oct 06, 2023 | This missense variant replaces asparagine with lysine at codon 80 in the LDLR type A repeat 2 ligand binding domain of the LDLR protein. This variant is also known as p.Asn59Lys in the mature protein. Computational prediction suggests that this variant may not impact protein structure and function (internally defined REVEL score threshold <= 0.5, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has been reported in a few individuals affected with familial hypercholesterolemia (PMID: 15241806, 27784735). This variant has not been identified in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance. - |
