Variant summary
Our verdict is Likely pathogenic. Variant got 6 ACMG points: 6P and 0B. PM1PM2PP3PP5
The NM_000527.5(LDLR):c.965A>T(p.Asn322Ile) variant causes a missense change. 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 Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. N322K) has been classified as Uncertain significance.

Familial hypercholesterolemia Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Jan 17, 2024 | This sequence change replaces asparagine, which is neutral and polar, with isoleucine, which is neutral and non-polar, at codon 322 of the LDLR protein (p.Asn322Ile). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with familial hypercholesterolemia (PMID: 20809525). ClinVar contains an entry for this variant (Variation ID: 251575). 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 with a positive predictive value of 95%. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. - |
