Variant summary
Our verdict is Pathogenic. Variant got 16 ACMG points: 16P and 0B. PM1PM2PM5PP3_ModeratePP5_Very_Strong
The NM_000527.5(LDLR):āc.1886T>Gā(p.Phe629Cys) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000657 in 152,198 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 Likely pathogenic (ā ā ). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. F629V) has been classified as Likely pathogenic.

Familial hypercholesterolemia Pathogenic:1
Likely pathogenic, criteria provided, single submitter | clinical testing | Invitae | Nov 29, 2022 | In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. 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: 252105). This missense change has been observed in individuals with familial hypercholesterolemia (PMID: 23375686; Invitae). This variant is present in population databases (no rsID available, gnomAD 0.01%). This sequence change replaces phenylalanine, which is neutral and non-polar, with cysteine, which is neutral and slightly polar, at codon 629 of the LDLR protein (p.Phe629Cys). - |
