Variant summary

Our verdict is Likely benign. The variant received -2 ACMG points: 0P and 2B. BP7BP4

This summary comes from the ClinGen Evidence Repository: The NM_000527.5(LDLR):c.1836C>T (p.Ala612=) variant is classified as likely benign for Familial Hypercholesterolemia by applying evidence code BP4 and BP7 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:BP4 - No REVEL, splicing evaluation required.Functional data on splicing not available.- Variant is exonic and at least 50bp downstream from canonical acceptor site but it does not create GT.- There is a GT nearby.MES scores: variant cryptic = -16.82, wt cryptic = -12.61, canonical donor = 4.48.Ratio variant cryptic/wt cryptic: -16.82/-12.61 = 1.33 --- it is above 1.1Ratio variant cryptic/canonical donor: -16.82/4.48 = -3.75 --- it is not above 0.9Variant is not predicted to alter splicing.BP7 - Variant is synonymous and meets BP4.

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]
