The probate court of the county in which a minor is found or in which the proposed permanent guardian is domiciled shall have the power to appoint a permanent guardian for a minor who has no natural guardian, testamentary guardian, or permanent guardian. In its discretion, the probate court of the county in which the petition for appointment of a permanent guardian is filed may transfer the case to the probate court of any other county in this state if such transfer would serve the best interest of the minor.
