Variant summary
Our verdict is Pathogenic. Variant got 18 ACMG points: 18P and 0B. PVS1PM2PP5_Very_Strong
The NM_000527.5(LDLR):c.1200C>A(p.Tyr400Ter) variant causes a stop gained change involving the alteration of a non-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 Pathogenic (★★). Synonymous variant affecting the same amino acid position (i.e. Y400Y) has been classified as Likely benign. Variant results in nonsense mediated mRNA decay.

Familial hypercholesterolemia Pathogenic:2
Pathogenic, criteria provided, single submitter | clinical testing | Color Diagnostics, LLC DBA Color Health | Nov 16, 2022 | This variant changes 1 nucleotide in exon 9 of the EGF precursor homology domain of the LDLR gene, creating a premature translation stop signal. This variant is expected to result in an absent or non-functional protein product. This variant has been reported in individuals affected with familial hypercholesterolemia (PMID: 15241806, 16250003, 18096825). It has also been reported in an individual suspected to be affected with familial hypercholesterolemia (PMID: 34037665). 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. - |
Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Sep 18, 2023 | For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 251728). This variant is also known as p.Y379X. This premature translational stop signal has been observed in individuals with familial hypercholesterolemia (PMID: 15241806, 16250003, 18096825; Invitae). This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Tyr400*) in the LDLR gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in LDLR are known to be pathogenic (PMID: 20809525, 28645073). - |
