July 31 (Reuters) - 23andMe co-founder and chief

executive Anne Wojcicki made a non-binding proposal to the board

to acquire all of the company's outstanding shares not already

owned by her or her affiliates for $0.40 per share, a filing

showed on Wednesday.

In April, Wojcicki notified the members of the board's

special committee of her intention to make an offer for the

genetic testing firm and take it private.

Wojcicki also had indicated that she was working with

advisers and intended to begin speaking to potential partners

and financing sources.

The proposal, which Wojcicki made on July 29, indicated that

she continued to have discussions with potential equity

financing sources, the filing showed.

The offer is conditioned upon approval of the company's

special committee and there can be no assurance that the

proposal will result in any definitive agreement, transaction or

any other strategic alternative, the filing said.

In the proposal, Wojcicki again stated that she would not

expect to support any alternative transaction.
