Hi All, I encountered discrepancies in clinvar annotations, leading to inconsistencies:
Discrepancies between locally downloaded datasets from clinvar and dbNSFP_CLINSIG and their respective web versions were noted. For instance, the variant (chr2:21006288:C:A) was labeled as Pathogenic in the downloaded datasets but not in the clinvar website. Conversely, chr2:21006288:C:T was marked as Conflicting_interpretations_of_pathogenicity in the downloaded datasets but deemed pathogenic on the clinvar website.
Variants also exhibited discordance between the downloaded clinvar and dbNSFP_CLINSIG datasets, even though they were based on the same version.
Can someone please help me understand why this issue?

What are the versions of the downloaded dataset and the one online?
The one downloaded was from 2022-04-30 for both dbNSFP and Clinvar. Web version is from 2023 (https://www.ncbi.nlm.nih.gov/clinvar/variation/17890/#id_second)
Look for additional pieces of evidence submitted in the time between - they're the reason you see a different CLINSIG value.
If you are certain about the discrepancy then reach out to clinvar support at clinvar at ncbi.nlm.nih.gov
