aa position reference

[umasaxena]

Migmap results show position of amino acid (pos.aa) where the changes (from.aa) occur due to somatic hypermutations to another amino acid (to.aa). I am trying to get the amino acid reference sequences for human IGH,IGL,IGK run. Please let me know how to get this done.

I require this information to quantify the number of significant somatic mutations at the amino acid level and be able to visualize it. The visualization plan is to have x axis of reference amino acid sequence and Y axis of 20 AA + stop & undetermined.
