Search engine giant Google has invested $3.2 million in genetics start-up 23andMe, which was founded by Google CEO Sergey Brin's wife Anne Wojcicki.

The new company, which has thus far received a total of $10.2 million in finance from Google's investment arm Google Ventures, raised a total of $22 million in this recent round of funding.

In a US Securities and Exchange Commission filing, Google said it had taken part in a Series C preferred financing round and continues to hold a minority stake in 23andMe, ABC news reports.

The company added that a new lead investor had determined the valuation of the investment, not Google. As of yet the name of the new majority stakeholder has not been revealed. 

Apart from Google and the unnamed lead investor, Johnson & Johnson Development Corporation and New Enterprise Associates also participated in the latest round of funding.

The company, which has raised more than $44 million since its inception, has also received $3.4 million personally from Sergey Brin.
