How to rank/prioritize inversions? #223
Comments
Thank you for sharing your point of view. Really interesting debate on how to rank/prioritize "inversions"! I'm definitely not an expert on SV ranking, so the discussion is open.
Absolutely, you're right.
No.

@jbmtp @thomasguignard @jmuller: |
I agree with @lgmgeo. @lgmgeo, let's think about this improvement: AnnotSV could assume to apply a "pseudo-ACMG" class to INV/INS and others exotic SV.
Alternatively, knotAnnotSV could apply this "pseudo-ACMG" classification. Another consideration about INV is related to its size. Big INVs may affect TAD structure/position and the affected genes expression. |
The most difficult thing will be to establish the right weightings for each criterion. We cannot rely on ACMG's work for inv/ins. |
Thank you very much for you insights! So then, would you say, following the same logic, that columns B_gain_source, B_gain_coord and B_gain_AFmax as well as P_gain_source, P_gain_coord and P_gain_AFmax are mostly informational? Because there are examples in which a pathogenic duplication can be contained within a benign one (see pic) However, I would consider B_loss_source, B_loss_coord and B_loss_AFmax as well as P_loss_source, P_loss_coord and P_loss_AFmax quite reliable predictors of a deletion being benign or pathogenic (it would be very rare to have a pathogenic deletion contained within a benign one for deletions larger than 50bp). Am I wrong? Thanks again for any thoughts! (I was not sure if I should keep this within this issue, hope it is fine) |
Actually, for gain and loss, we follow the ACMG / Clingen recommendation. Of course, you're right, a pathogenic duplication can be contained within a benign one. |
I see, so we should always refer to ACMG class. We were hoping to rank VUS (ACMG=3) looking at B/P_gain/loss/inv columns, that is why we were trying to understand better the criteria to annotate these columns and the info they could give us. Thanks!! |
Question from an AnnotSV user:
I am writing to you because we have annotated our SV tables with AnnotSV and we are not sure of in which case you consider that a benign inversion completely overlaps the SV to annotate so that the columns B_inv_source, B_inv_coord and B_inv_AFmax get anotated. Apparently, coordinates of both do not match and it seems problematic to us consider an inversion benign because it is contained within a known benign inversion, since the known benign inversion may leave a gene intact while the contained one may cut it in some point. Could you explain a bit your approach?
Basically, we would like to know if it is reliable to use these columns to assume an inversion is benign when the columns show other benign inversions overlapping.
Thank you very much for any help,
