Variant summary
Our verdict is Pathogenic. Variant got 18 ACMG points: 18P and 0B. PM1PM2PM5PP3_StrongPP5_Very_Strong
The NM_000527.5(LDLR):c.1844A>T(p.Glu615Val) variant causes a missense, splice region 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. 3/3 splice prediction tools predicting alterations to normal splicing. 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. E615K) has been classified as Likely pathogenic.

Pathogenic, criteria provided, single submitter | clinical testing | Ambry Genetics | Nov 13, 2020 | The p.E615V pathogenic mutation (also known as c.1844A>T), located in coding exon 12 of the LDLR gene, results from an A to T substitution at nucleotide position 1844. The glutamic acid at codon 615 is replaced by valine, an amino acid with dissimilar properties. This variant segregates with familial hypercholesterolemia and has been detected in multiple affected individuals (Marduel M et al. Hum Mutat, 2010 Nov;31:E1811-24). Another alteration at the same codon, p.E615K (c.1843G>A), has been detected in multiple individuals with familial hypercholesterolemia (Fouchier SW et al. Hum Genet, 2001 Dec;109:602-15; Huijgen R et al. Hum Mutat, 2010 Jun;31:752-60). This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Based on the supporting evidence, this alteration is interpreted as a disease-causing mutation. - |
