       by Section 16(a) of the Securities and Exchange Act of 1934 or any rule
       or regulation of the SEC; and

(2)    execute for and on behalf of the undersigned, in the undersigned's
       capacity as an officer and/or director of Invitae Corporation (the

       may be necessary or desirable to complete and execute any such Forms 3, 4
       and 5, Form 144, and Schedule 13D or Schedule 13G (including amendments
       thereto) and timely file such Forms or Schedules with the SEC and any
       stock exchange, self- regulatory association or any other authority; and

(4)    take any other action of any type whatsoever in connection with the
       foregoing that, in the opinion of such attorney-in-fact, may be of
       benefit to, in the best interest of, or legally required of the
       undersigned, it being understood that the documents executed by the
       attorney-in-fact on behalf of the undersigned pursuant to this Power of
       Attorney shall be in such form and shall contain such terms and
       conditions as the attorney-in-fact may approve in the attorney-in-fact's
       discretion.

       The undersigned hereby grants to the attorney-in-fact full power and
authority to do and perform all and every act and thing whatsoever requisite,
necessary or proper to be done in the exercise of any of the rights and powers
herein granted, as fully to all intents and purposes as the undersigned might or
could do if personally present, with full power of substitution or revocation,
hereby ratifying and confirming all that the attorney-in-fact shall lawfully do
or cause to be done by virtue of this Power of Attorney and the rights and
powers herein granted.  The undersigned acknowledges that the foregoing
attorney-in-fact, in serving in such capacity at the request of the undersigned,

information furnished orally or in writing by the undersigned to the attorney-
in-fact.  The undersigned also agrees to indemnify and hold harmless such
attorney-in-fact against any losses, claims, damages or liabilities (or actions
in these respects) that arise out of or are based upon any untrue statements or
omissions of necessary facts in the information provided by the undersigned to
such attorney-in fact for purposes of executing, acknowledging, delivering or
filing Form 4 or Form 144 (including amendments thereto) and agrees to reimburse
the attorney-in-fact on demand for any legal or other expenses reasonably
incurred in connection with investigating or defending against any such loss,
claim, damage, liability or action.

       This Power of Attorney shall remain in full force and effect until the
undersigned is no longer required to file Forms 3, 4 and 5 with respect to the
undersigned's holdings of and transactions in securities issued by the Company,
unless earlier revoked by the undersigned in a signed writing delivered to the
foregoing attorney-in-fact.

       IN WITNESS WHEREOF, the undersigned has caused this Power of Attorney to
be executed as of the date written below.
