Variant summary
Our verdict is Pathogenic. Variant got 16 ACMG points: 16P and 0B. PM1PM2PP3_StrongPP5_Very_Strong
The NM_000527.5(LDLR):c.1514G>A(p.Gly505Asp) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.000000684 in 1,461,888 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 (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. G505A) has been classified as Uncertain significance.

Likely pathogenic, criteria provided, single submitter | clinical testing | Women's Health and Genetics/Laboratory Corporation of America, LabCorp | Nov 14, 2023 | Variant summary: LDLR c.1514G>A (p.Gly505Asp) results in a non-conservative amino acid change in the encoded protein sequence. Five of five in-silico tools predict a damaging effect of the variant on protein function. The variant was absent in 251454 control chromosomes. c.1514G>A has been reported in the literature in individuals homozygous and heterozygous individuals affected with Familial Hypercholesterolemia (Lind_2002, Maglio_2014, Pavanello_2019). While both heterozygous and homozygous individuals displayed features including high cholesterol and cardiovascular disease, only some homozygotes had the full phenotype including Tendon xanthomas, leading authors to speculate the variant may result in a milder phenotype. Because of the presence of phenocopies in these patients with milder disease, this data cannot provide unequivocal conclusions about pathogenicity. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. One submitter has cited clinical-significance assessments for this variant to ClinVar after 2014 and has classified the variant as likely pathogenic. Based on the evidence outlined above, the variant was classified as likely pathogenic. - |
