Variant summary
Our verdict is Pathogenic. Variant got 18 ACMG points: 18P and 0B. PVS1PM2PP5_Very_Strong
The NM_004525.3(LRP2):c.1093C>T(p.Arg365Ter) variant causes a stop gained change. The variant allele was found at a frequency of 0.0000109 in 1,461,804 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 Pathogenic (★★). Synonymous variant affecting the same amino acid position (i.e. R365R) has been classified as Likely benign. Variant results in nonsense mediated mRNA decay.

Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Aug 02, 2023 | For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 9457). This premature translational stop signal has been observed in individual(s) with Donnai-Barrow syndrome (PMID: 17632512, 25682901). This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Arg365*) in the LRP2 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in LRP2 are known to be pathogenic (PMID: 17632512, 25682901). - |
