RCV001195926 | SCV001366350 | likely pathogenic | Age related macular degeneration 2 | 2019-09-05 | criteria provided, single submitter | clinical testing | This variant was classified as: Likely pathogenic. The following ACMG criteria were applied in classifying this variant: PM1,PM2,PP3,PP5. |
Invitae | RCV000085626 | SCV001590828 | pathogenic | not provided | 2024-01-19 | criteria provided, single submitter | clinical testing | This sequence change replaces proline, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 143 of the ABCA4 protein (p.Pro143Leu). This variant is present in population databases (rs62646860, gnomAD 0.003%). This missense change has been observed in individuals with ABCA4-related conditions (PMID: 14517951, 25412400, 29178665, 29854428). ClinVar contains an entry for this variant (Variation ID: 99273). 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 ABCA4 protein function with a positive predictive value of 95%. For these reasons, this variant has been classified as Pathogenic. |

RCV003330431 | SCV004037681 | pathogenic | Stargardt disease | 2023-08-29 | criteria provided, single submitter | clinical testing | Variant summary: ABCA4 c.428C>T (p.Pro143Leu) results in a non-conservative amino acid change in the encoded protein sequence. Four of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 8e-06 in 251456 control chromosomes. c.428C>T has been reported in the literature in multiple individuals affected with Stargardt Disease (e.g. Abed_2018, DelPozo_2022, Ibanez_2021, Jaakson_2003, Smaragda_2018) and Cone Dystrophy (Consugar_2015). These data indicate that the variant is very likely to be associated with disease. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publications have been ascertained in the context of this evaluation (PMID: 25412400, 35119454, 33369172, 14517951, 29854428, 29178665).Three submitters have cited clinical-significance assessments for this variant to ClinVar after 2014. All submitters classified the variant as pathogenic/likely pathogenic. Based on the evidence outlined above, the variant was classified as pathogenic. |
