       Preliminary Proxy Statement on Schedule 14A

       Acquisition of Viridian, page 13

   1.                                                   It does not appear that
you have filed the exclusive license agreement with ImmunoGen,
                                                        Inc. as an exhibit to
any of your filings and it is not clear whether this agreement will be
                                                        filed when Miragen
shareholders will be asked to vote on the Conversion Proposal.
                                                         Please file that
agreement as an exhibit to an appropriate filing or explain to us the basis
                                                        for your determination
that it is not required to be filed. If you believe the agreement is
                                                        not required to be
filed, please include in your explanation a detailed analysis supporting
                                                        your belief that your
plans to develop and commercialize VRDN-001 are not substantially
                                                        dependent on that
license agreement.
   2.                                                   We note your disclosure
that you have included a pro forma balance sheet as Annex C to
                                                        your proxy statement
for informational purposes only. Please revise this statement so that
                                                        it does not imply to
shareholders that you are not responsible for this disclosure.

3.    We note your disclosure that in approving the acquisition of Viridian and
the related
      financing, the board of directors considered the pros and cons of these
transactions versus
      other alternatives. Please expand your disclosure to include the
consideration that the
      board gave to the pros and cons of acquiring Viridian through the
issuance of convertible
      preferred stock instead of through a traditional acquisition where the
stockholders could
      vote to approve or disapprove of the acquisition and the issuance of
securities prior to the
      consummation of the acquisition. The expanded disclosure should include
why the board
      viewed the preferred stock structure as preferable to a traditional
structure, the business
      reasons for preferring the current structure, and why the board chose to
structure the
      transaction in a way that would not allow the stockholders of the company
to vote and
      express their approval or disapproval on the acquisition itself.
4.    We note that your Proposal No. 1 Approval of Conversion Proposal is a
result of your
      acquisition of Viridian. Although we note your brief discussion of the
background of the
      transactions in this section, please refer to Note A of Schedule 14A and
revise your proxy
      statement to provide all of the material information relating to Viridian
and the acquisition
      that is required by Item 14(b)(7) of Schedule 14A, including the
information required by
      Items 1005(b) and 1011(a)(1) of Regulation M-A.
        We remind you that the company and its management are responsible for
the accuracy
and adequacy of their disclosures, notwithstanding any review, comments, action
or absence of
action by the staff.

       You may contact Tim Buchmiller at (202) 551-3635 or Joe McCann at (202)

you have questions.
