Exhibit 23.1
Statement Regarding Consent of Arthur Andersen LLP

BioMarin  Pharmaceutical  Inc.'s Form 8-K/A,  filed herewith,  includes  audited
financial  statements of Glyko  Biomedical Ltd. as of December 31, 2001 together
with the  accompanying  audit report of Arthur  Andersen LLP.  After  reasonable
efforts,  we have not been able to obtain the consent of Arthur  Andersen LLP to
the  incorporation  by reference  of its audit  report dated  February 21, 2002.
Therefore,  in reliance on Rule 437a  promulgated  under the  Securities  Act of
1933, as amended (the "Securities  Act"), we have dispensed with the requirement
to file the  reissued  reports  of Arthur  Andersen  LLP with  respect  to these
financial  statements.  As a  result,  you will not be able to  recover  against
Arthur  Andersen  LLP under  Section  11 of the  Securities  Act for any  untrue
statement of a material  fact  contained in these  financial  statements  or any
omissions to state a material fact required to be stated therein.
