<div class="">We’re trying to validate some mutations and see other co-located variants by using the VEP REST service for GRCh37, like this:</div>

<div class=""><br class="">

<div class="">If I include the deleted sequence in the hgvs syntax, I get a different error:</div>

<div class="">This is strange because shouldn’t the transcript coordinates ‘ENST00000460680.1:c.661-783+1’ correspond to ‘3:g.52440268-52440391’? But these aren’t the coordinates returned and the allele sequence is inconsistent with the input.</div>
