Variant summary
Our verdict is Pathogenic. Variant got 16 ACMG points: 16P and 0B. PVS1PP5_Very_Strong
The NM_000350.3(ABCA4):c.3211_3212insGT(p.Ser1071CysfsTer14) variant causes a frameshift change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000397 in 1,614,056 control chromosomes in the GnomAD database, with no homozygous occurrence. Variant has been reported in ClinVar as Likely pathogenic (★★). Synonymous variant affecting the same amino acid position (i.e. S1071S) has been classified as Likely benign. Variant results in nonsense mediated mRNA decay.

Pathogenic, criteria provided, single submitter | clinical testing | GeneDx | Oct 25, 2021 | Frameshift variant predicted to result in protein truncation or nonsense mediated decay in a gene for which loss-of-function is a known mechanism of disease; Not observed at a significant frequency in large population cohorts (Lek et al., 2016); This variant is associated with the following publications: (PMID: 23755871, 11527935, 9054934, 29555955, 24265693, 29186038, 28041643, 29925512, 30718709, 30798147, 32581362) - |

Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Jan 11, 2024 | This sequence change creates a premature translational stop signal (p.Ser1071Cysfs*14) 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). This variant is present in population databases (rs387906385, gnomAD 0.004%). This premature translational stop signal has been observed in individual(s) with retinal disease including early onset severe retinal dystrophy, autosomal recessive retinitis pigmentosa, and Stargardt disease (PMID: 23755871, 29186038). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. This variant is also known as c.3211_3212insGT. ClinVar contains an entry for this variant (Variation ID: 372290). For these reasons, this variant has been classified as Pathogenic. - |
