Variant summary

Our verdict is Uncertain significance. Variant got 3 ACMG points: 6P and 3B. PM1PM2PM5BP4BP6_Moderate

The NM_000527.5(LDLR):​c.1236G>A​(p.Met412Ile) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000411 in 1,461,590 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. M412T) has been classified as Likely pathogenic.

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]

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 3 ACMG points.

PM1
In a strand (size 7) in uniprot entity LDLR_HUMAN there are 14 pathogenic changes around while only 1 benign (93%) in NM_000527.5
PM2
Very rare variant in population databases, with high coverage;
PM5
Other missense variant is known to change same aminoacid residue: Variant chr19-11113326-T-C is described in Lovd as [Likely_pathogenic].
BP4
Computational evidence support a benign effect (MetaRNN=0.29781598).
BP6
Variant 19-11113327-G-A is Benign according to our data. Variant chr19-11113327-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 251746.Status of the report is criteria_provided_single_submitter, 1 stars. Variant chr19-11113327-G-A is described in Lovd as [Likely_benign].
