Variant summary
Our verdict is Likely pathogenic. Variant got 9 ACMG points: 9P and 0B. PM1PM2PP3_StrongPP5
The NM_000527.5(LDLR):āc.1640T>Cā(p.Leu547Pro) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.000000684 in 1,461,516 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Synonymous variant affecting the same amino acid position (i.e. L547L) has been classified as Likely benign.

Hypercholesterolemia, familial, 1 Pathogenic:2
Likely pathogenic, criteria provided, single submitter | clinical testing | Human Genome Sequencing Center Clinical Lab, Baylor College of Medicine | Sep 19, 2017 | This c.1640T>C (p.Leu547Pro) variant in the LDLR gene has been reported in multiple individuals with familial hypercholesterolemia and has been shown to segregate with affected status in one family (PMID: 22881376, 28161202). The c.1640T>C variant is not detected in the general population and leucine at position 547 of the LDLR protein is highly evolutionarily conserved. The c.1640T>C (p.Leu547Pro) variant in the LDLR gene is classified as likely pathogenic. - |

Familial hypercholesterolemia Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Color Diagnostics, LLC DBA Color Health | Apr 02, 2019 | This missense variant (also known as p.Leu526Pro in the mature protein) is located in the fourth LDLR type B repeat of the EGF precursor homology domain of the LDLR protein. Computational prediction tools and conservation analyses suggest that this variant may have deleterious impact on the protein function. Computational splicing tools suggest that this variant may not impact RNA splicing. To our knowledge, functional assays have not been performed for this variant. This variant has been reported in an individual affected with familial hypercholesterolemia and her affected father (PMID: 28161202). This variant has not been identified in the general population by the Genome Aggregation Database (gnomAD). Although available evidence suggests this variant may be associated with disease, additional studies are necessary to determine the pathogenicity of this variant conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance. - |
