Athena Diagnostics	RCV000081763	SCV000614384	pathogenic	not provided	2022-12-07	criteria provided, single submitter	clinical testing	This variant is expected to result in the loss of a functional protein. This variant is one of the most common pathogenic variants associated with autosomal dominant optic atrophy (ADOA; PMID: 11440989, 22857269), and therefore the frequency of this variant in the general population is consistent with pathogenicity (Genome Aggregation Database (gnomAD), Cambridge, MA (URL: http://gnomad.broadinstitute.org)). This variant has been reported to exhibit reduced penetrance (PMID: 11440989). Assessment of experimental evidence suggests this variant results in abnormal protein function. (PMID: 18222991) This variant occurs with an alternate explanation for disease significantly less often than expected, suggesting this variant may be associated with disease.

Invitae	RCV000081763	SCV001591733	pathogenic	not provided	2024-01-26	criteria provided, single submitter	clinical testing	This sequence change creates a premature translational stop signal (p.Val903Glyfs*3) in the OPA1 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in OPA1 are known to be pathogenic (PMID: 11440988, 20157015, 20952381, 25012220). This variant is present in population databases (rs745560444, gnomAD 0.007%). This premature translational stop signal has been observed in individuals with dominant optic atrophy (PMID: 11017079, 26385429). It has also been observed to segregate with disease in related individuals. This variant is also known as c.2708delTTAG and c.2873_2876delTTAG (p.V958Gfs*3). ClinVar contains an entry for this variant (Variation ID: 5082). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. For these reasons, this variant has been classified as Pathogenic.

3billion	RCV000005387	SCV002318897	pathogenic	Autosomal dominant optic atrophy classic form	2022-03-22	criteria provided, single submitter	clinical testing	Canonical splice site: predicted to alter splicing and result in a loss or disruption of normal protein function through nonsense-mediated decay (NMD) or protein truncation. Multiple pathogenic variants are reported downstream of the variant. The variant has been observed in multiple (>3) similarly affected unrelated individuals (PMID: 20417570, 14961560). Therefore, this variant is classified as pathogenic according to the recommendation of ACMG/AMP guideline.

PreventionGenetics, part of Exact Sciences	RCV004532291	SCV004120905	pathogenic	OPA1-related disorder	2023-08-31	criteria provided, single submitter	clinical testing	The OPA1 c.2873_2876delTTAG variant is predicted to result in a frameshift and premature protein termination (p.Val958Glyfs*3). This variant is also often denoted as c.2708_2711delTTAG (p.Val903Glyfs*3) in the alternate transcript NM_015560.2. This variant has been reported many times as causative for autosomal dominant optic atrophy (see for examples Delettre et al. 2000. PubMed ID: 11017079; Pretegiani et al. 2011. PubMed ID: 21646330; Gaier et al. 2017. PubMed ID: 28848318; Lin et al. 2021. PubMed ID: 34573359). This variant has also been reported in the compound heterozygous state in an individual with early-onset Behr syndrome and the unaffected mother was a carrier of this variant, suggesting there may be incomplete penetrance (Bonneau et al. 2014. PubMed ID: 25012220). This variant is reported in 0.0062% of alleles in individuals of European (Non-Finnish) descent in gnomAD (http://gnomad.broadinstitute.org/variant/3-193384956-CAGTT-C). Frameshift variants in OPA1 are expected to be pathogenic, and this variant has been classified as pathogenic by multiple independent submitters to the ClinVar database (https://www.ncbi.nlm.nih.gov/clinvar/variation/5082). Given all the evidence, we interpret c.2873_2876del (p.Val958Glyfs*3) as pathogenic.
