Variant summary

Our verdict is Benign. The variant received -9 ACMG points: 0P and 9B. BA1BP4

This summary comes from the ClinGen Evidence Repository: The NM_000527.5(LDLR):c.941-39C>T variant is classified as Benign for Familial Hypercholesterolemia by applying evidence codes BA1 and 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: BA1: FAF=0.005249 (0.5249%) in European (Non-Finnish) exomes (gnomAD v2.1.1). So BA1 is met.BP4: The variant is not predicted to affect the splicing process by SpliceAI. So, BP4 is met. LINK:https://erepo.genome.network/evrepo/ui/classification/CA030745/MONDO:0007750/013

Genes affected

LDLR (HGNC:6547): (low density lipoprotein receptor) The low density lipoprotein receptor (LDLR) gene family consists of cell surface proteins involved in receptor-mediated endocytosis of specific ligands. The encoded protein is normally bound at the cell membrane, where it binds low density lipoprotein/cholesterol and is taken into the cell. Lysosomes release the cholesterol, which is made available for repression of microsomal enzyme 3-hydroxy-3-methylglutaryl coenzyme A (HMG CoA) reductase, the rate-limiting step in cholesterol synthesis. At the same time, a reciprocal stimulation of cholesterol ester synthesis takes place. Mutations in this gene cause the autosomal dominant disorder, familial hypercholesterolemia. Alternate splicing results in multiple transcript variants.[provided by RefSeq, May 2022]
