RCV000085833 | SCV000617269 | pathogenic | not provided | 2017-07-10 | criteria provided, single submitter | clinical testing | The c.6601_6602delAG variant in the ABCA4 gene has been reported previously, with no second variant identified, in a female patient with onset of atypical cone-rod dystrophy at age 8 (Maugeri et al., 2000; Klevering et al., 2002). This variant causes a frameshift starting with codon Arginine 2201, changes this amino acid to an Alanine residue, and creates a premature Stop codon at position 49 of the new reading frame, denoted p.Arg2201AlafsX49. The c.6601_6602delAG variant is predicted to cause loss of normal protein function either through protein truncation or nonsense-mediated mRNA decay. This variant is not observed in large population cohorts (Lek et al., 2016; 1000 Genomes Consortium et al., 2015; Exome Variant Server). We interpret c.6601_6602delAG as a pathogenic variant. |

RCV000085833 | SCV001578715 | pathogenic | not provided | 2022-10-17 | criteria provided, single submitter | clinical testing | For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 99472). This variant is also known as Glu2200del2 aggGA. This premature translational stop signal has been observed in individual(s) with retinitis pigmentosa (PMID: 20647261). This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Arg2201Alafs*49) in the ABCA4 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in ABCA4 are known to be pathogenic (PMID: 10958761, 24938718, 25312043, 26780318). |
