Mastermind supports GRCh37 and GRCh38 searches for SNVs/indels. Variants can be entered directly in the search box as shown below in GRCh37 and GRCh38, respectively:

To search for genomic coordinates in Mastermind, enter them in the search bar with the appropriate sequence identifier or modify the URL directly as in the link below:


where can be taken from the list below and substituted into the URL.

For example, a search on chromosome 1 in build GRCh37/hg19 would look like this:

Searching by genomic coordinates will list references for variants mapped to alternate transcripts. We recommend adding the gene of interest as another search term to reduce off-target matches.
