GeneDx RCV000085793 SCV000321328 pathogenic not provided 2021-05-25 criteria provided, single submitter clinical testing Identified in individuals referred for genetic testing at GeneDx and in published literature with autosomal recessive ABCA4-related retinal dystrophies, including Stargardt disease and cone-rod dystrophy (Webster et al., 2001; Birch et al., 2001); Variant has also been observed in individuals with retinal dystrophy who had other disease-causing ABCA4 variants or variants in another gene that may have also contributed to the phenotype (Fishman et al., 1999; Eisenberger et al., 2013); Published functional studies demonstrate a damaging effect with reduced ATPase activity compared to wild type (Sun et al., 2000); Observed on 1.5451% (385/24918) alleles) from individuals of African background including one unaffected homozygous individual in large population cohorts, which is greater than expected for this disorder (Lek et al., 2016); This variant is associated with the following publications: (PMID: 20647261, 11846518, 11328725, 17982420, 10206579, 24265693, 11017087, 22995991)

Illumina Clinical Services Laboratory,Illumina RCV001098370 SCV001254730 uncertain significance ABCA4-Related Disorders 2018-01-12 criteria provided, single submitter clinical testing This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation. A literature search was performed for the gene, cDNA change, and amino acid change (if applicable). No publications were found based on this search. This variant was therefore classified as a variant of unknown significance for this disease.
