Information about variation-scan

Scan variant sequences with position specific scoring matrices (PSSM) and report variations that affect the binding score, in order to predict regulatory variants.

Matrix collections

A set conformed by different motifs representing binding profiles for several transcription factors will be used to scan the variants. Provide your own motifs collection or select one to be used.
