Variant summary
Our verdict is Pathogenic. Variant got 14 ACMG points: 14P and 0B. PM1PM2PM5PP3_StrongPP5_Strong
The NM_000527.5(LDLR):c.1576C>A(p.Pro526Thr) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. P526H) has been classified as Likely pathogenic.

Hypercholesterolemia, familial, 1 Pathogenic:1Uncertain:1
Uncertain significance, reviewed by expert panel | curation | ClinGen Familial Hypercholesterolemia Variant Curation Expert Panel | Jan 18, 2022 | NM_000527.5(LDLR):c.1576C>A (p.Pro526Thr) variant is classified as variant of Uncertain significance for Familial Hypercholesterolemia by applying evidence codes (PM2, PP3 and PP4) 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: PM2 - This variant is absent from gnomAD (gnomAD v2.1.1). PP3 - REVEL = 0.951. PP4 - Variant meets PM2. Identified in 1 FH case with clinical diagnosis of probable heterozygous hypercholesterolemia by DLCN score (DLCN = 8) from PMID 32770674. - |

Familial hypercholesterolemia Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Jun 06, 2023 | For these reasons, this variant has been classified as Pathogenic. This variant disrupts the p.Pro526 amino acid residue in LDLR. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 1301956, 9259195, 11462246, 27497240; Invitae). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt LDLR protein function. ClinVar contains an entry for this variant (Variation ID: 251903). This missense change has been observed in individuals with familial hypercholesterolemia (PMID: 32770674; Invitae). This variant is not present in population databases (gnomAD no frequency). This sequence change replaces proline, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 526 of the LDLR protein (p.Pro526Thr). - |
