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]
MIR6886 (HGNC:50121): (microRNA 6886) microRNAs (miRNAs) are short (20-24 nt) non-coding RNAs that are involved in post-transcriptional regulation of gene expression in multicellular organisms by affecting both the stability and translation of mRNAs. miRNAs are transcribed by RNA polymerase II as part of capped and polyadenylated primary transcripts (pri-miRNAs) that can be either protein-coding or non-coding. The primary transcript is cleaved by the Drosha ribonuclease III enzyme to produce an approximately 70-nt stem-loop precursor miRNA (pre-miRNA), which is further cleaved by the cytoplasmic Dicer ribonuclease to generate the mature miRNA and antisense miRNA star (miRNA*) products. The mature miRNA is incorporated into a RNA-induced silencing complex (RISC), which recognizes target mRNAs through imperfect base pairing with the miRNA and most commonly results in translational inhibition or destabilization of the target mRNA. The RefSeq represents the predicted microRNA stem-loop. [provided by RefSeq, Sep 2009]

This variant causes a G to A nucleotide substitution at the -1 position of intron 9 of the LDLR gene. Splice site prediction tools suggest that this variant may have a significant impact on RNA splicing. A quantitative RNA study has shown that this variant causes a deletion of the first seven nucleotides of exon 10 due to a cryptic splice acceptor activation, and is expected to cause a frameshift and premature truncation (PMID: 10090473). This variant has been reported in hundreds of individuals affected with familial hypercholesterolemia (PMID: 7616128, 9254862, 10090473, 10735632, 11668640, 11857755, 12436241, 15241806, 21382890, 21475731, 25154303, 33955087, 34037665). It has been shown that this variant segregates with disease in multiple affected individuals in two families (PMID: 9254862, 25154303). This variant has not been identified in the general population by the Genome Aggregation Database (gnomAD). Loss of LDLR function is a known mechanism of disease (clinicalgenome.org). Based on the available evidence, this variant is classified as Pathogenic. -

The LDLR c.1359-1G>A variant disrupts a canonical splice-acceptor site and interferes with normal LDLR mRNA splicing. This variant has been reported in the published literature in individuals affected with hypercholesterolemia (PMIDs: 11857755 (2002), 11668640 (2001), 10735632 (2000), 7616128 (1995)). The variant has been reported to segregate with hypercholesterolemia in an affected family (PMID: 9254862 (1997). A functional study indicates that this variant impacts protein function (PMID: 19208450 (2009)). This variant has not been reported in large, multi-ethnic general populations (Genome Aggregation Database, http://gnomad.broadinstitute.org). Based on the available information, this variant is classified as pathogenic. -

This sequence change affects an acceptor splice site in intron 9 of the LDLR gene. RNA analysis indicates that disruption of this splice site induces altered splicing and may result in an absent or altered protein product. This variant is not present in population databases (gnomAD no frequency). Disruption of this splice site has been observed in individuals with familial hypercholesterolemia (PMID: 9254862, 10735632, 11668640, 11857755, 15241806, 21382890, 21475731, 22390909, 25154303). It has also been observed to segregate with disease in related individuals. Invitae Evidence Modeling of clinical and family history, age, sex, and reported ancestry of multiple individuals with this LDLR variant has been performed. This variant is expected to be pathogenic with a positive predictive value of at least 99%. This is a validated machine learning model that incorporates the clinical features of 363,995 individuals referred to our laboratory for LDLR testing. ClinVar contains an entry for this variant (Variation ID: 162499). Studies have shown that disruption of this splice site results in activation of a cryptic acceptor splice site, and produces a non-functional protein and/or introduces a premature termination codon (PMID: 10090473). For these reasons, this variant has been classified as Pathogenic. -

Significance:Pathogenic
Review Status:criteria provided, single submitter
Collection Method:clinical testing

The c.1359-1G>A variant in LDLR has been reported in >80 individuals with famili al hypercholesterolemia (FH), segregated with disease in 8 affected relatives fr om 3 families (Peeters 1995, Lombarid 1995 and 2000, Garcia-Garcia 2001, Braenne 2015), and has been identified in 1/8600 European American chromosomes by the N HLBI Exome Sequencing Project (http://evs.gs.washington.edu/EVS/; dbSNP rs139617 694). This variant occurs in the invariant region (+/- 1,2) of the splice consen sus sequence and is predicted to cause altered splicing leading to an abnormal o r absent protein. Heterozygous loss of LDLR function is an established disease m echanism in familial hypercholesterolemia. In summary, this variant meets our cr iteria to be classified as pathogenic for familial hypercholesterolemia in an au tosomal dominant manner.

The c.1359-1G>A intronic pathogenic mutation results from a G to A substitution one nucleotide upstream from coding exon 10 of the LDLR gene. This alteration has been previously reported in unrelated individuals, as well as co-segregating in families, with hypercholesterolemia and has been reported as originating in the Netherlands (Peeters AV et al. Hum Genet. 1997;100(2):266-70; Kusters DM et al. Neth Heart J. 2011;19(4):175-182; Br&aelig;nne I et al. BMC Cardiovasc Disord. 2014;14:108; Br&aelig;nne I et al. Eur. J. Hum. Genet., 2016 Feb;24:191-7). One functional study suggested this alteration results in a partial loss of mRNA, while another study reported this alteration as causing aberrant splicing in which the first 7 base pairs of exon 10 were deleted, predicting an early stop codon (Peeters AV et al. Hum Genet. 1997;100(2):266-70; R&oslash;dningen OK et al. Hum Mutat. 1999;13(3):186-96). In addition to the clinical data presented in the literature, alterations that disrupt the canonical splice site are expected to cause aberrant splicing, resulting in an abnormal protein or a transcript that is subject to nonsense-mediated mRNA decay. As such, this alteration is classified as a disease-causing mutation. -
