                               POWER OF ATTORNEY

     The undersigned, as a Section 16 reporting person of Alector, Inc. (the

          behalf, and submit to the Securities and Exchange Commission (the
          "SEC") a Form ID, including amendments thereto, and any other
          documents necessary or appropriate to obtain EDGAR codes and passwords
          enabling the undersigned to make electronic filings with the SEC of
          reports required by Section 16(a) of the Securities Exchange Act of
          1934 or any rule or regulation of the SEC;

     2.   complete and execute Forms 3, 4 and 5 and other forms and all
          amendments thereto as such attorney-in-fact shall in his discretion
          determine to be required or advisable pursuant to Section 16 of the
          Securities Exchange Act of 1934 (as amended) and the rules and
          regulations promulgated thereunder, or any successor laws and
          regulations, as a consequence of the undersigned's ownership,
          acquisition or disposition of securities of the Company; and

     3.   do all acts necessary in order to file such forms with the SEC, any

     The undersigned hereby ratifies and confirms all that said attorneys-in-
