Hi Ketan,

The online version of the VEP has a 750 variant limit - it sounds like
this might be the cause of the missing results.

The online version will provide you with results for the first 750
variants in your file, but not for those after this.

You should also note that if a variant does not fall within range
(5kb) of any transcripts, it is considered to be "intergenic" and will
not return any results at all.

Thanks

Will
