Listed Variant ClinVar IDs return 404 #1179
Description
I was talking with @larrybabb and we noticed that there were several ClinVar IDs for a variant. For example, CIViC variant ID 33 lists the following ClinVar IDs: 16609, 376282, 376280. The last two return 404 Not Found. BRAF V600E variant also has this issue, so we're assuming there are other variants that list ClinVar IDs that do not exist. We're not sure what these old ClinVar IDs were for. Should an update be made to only include ClinVar IDs that do not return 404?
