Search for variation in the human genome using HGVS nomenclature.
You may then proceed to submit a new variant, or add information to one already in the database. If you have multiple variants to submit, a batch form is available which can be submitted here.
Your submissions will be processed into ClinVar and assigned ClinVar accessions (SCV). Novel variant locations will also be accessioned in dbSNP or dbVar as appropriate.
You may also consider submitting directly to ClinVar; see http://www.ncbi.nlm.nih.gov/clinvar/docs/submit/ for information on where to send ClinVar submissions. ClinVar's submission template provides more opportunities to submit clinically relevant information. Please contact us if you have any questions.
When you submit an HGVS expression, we validate that the asserted allele in HGVS matches the allele on the HGVS sequence and then map the location to the current human reference genome. If your HGVS expression cannot be mapped to the current human reference genome, the submission will not be processed currently. We regret any inconvenience this may cause.
If the placement or the alignment is successful, the sequence variant is searched in dbSNP. The matching record, if found, is returned and you can choose to annotate it; otherwise, you can submit it to dbSNP as a new record.
