theodp writes "In 2008, Google co-founder Sergey Brin blogged that tests conducted by 23andme, the consumer genetics company headed by Brin's wife Anne Wojcicki (and bankrolled by Google), showed that he and his Parkinson's-afflicted mother both shared the G2019S mutation of the LRRK2 gene. 'It is clear that I have a markedly higher chance of developing Parkinson's in my lifetime than the average person,' Brin explained of the find. 'At the same time,' he added, 'research into LRRK2 looks intriguing.' Indeed. But now Nature reports that 23andme is raising hackles with the revelation that it has received its first patent, on a genetic mutation which Wojcicki explains, 'relates to our discovery of a variant in the SGK1 gene that may be protective against Parkinson’s disease in individuals who carry the rare risk-associated LRRK2 G2019S mutation.' Scientific American has more on the 23andme patent."
