The 23andMe Personal Genome Service (PGS) uses qualitative genotyping to detect select clinically relevant variants in genomic DNA isolated from human saliva collected from individuals ≥18 years for the purpose of reporting and interpreting genetic health risks, including the 23andMe PGS Genetic Health Risk Report for Hereditary Prostate Cancer (HOXB13-Related). The 23andMe PGS Genetic Health Risk Report for Hereditary Prostate Cancer (HOXB13- Related) is indicated for reporting of the G84E variant in the HOXB13 gene. The report describes if a person has the G84E variant and if a male is at increased risk for prostate cancer. The variant included in this report is most common in people of European descent. The test report does not describe a person's overall risk of developing any type of cancer, and the absence of a variant tested does not rule out the presence of other variants that may be cancer-related. This test is not a substitute for visits to a healthcare provider for recommended screenings or appropriate follow-up and should not be used for diagnosis, to determine any treatments or medical interventions.

The 23andMe Personal Genome Service (PGS) is an over-the-counter (direct-to-consumer), DNA testing service that provides information and tools for consumers to learn about and explore their DNA. The 23andMe Personal Genome Service (PGS) is a currently marketed, non-invasive genetic information service that combines qualitative genotyping data covering genetic ancestry, traits, and certain heritable health conditions from a single multiplex assay with descriptive information derived from peer reviewed, published genetic research studies. It is a home use, over-thecounter (direct-to-consumer) DNA testing service intended to provide information and tools for consumers to learn about and explore their DNA. Customer saliva is self-collected using the Oragene-Dx® Device manufactured by DNA Genotek, Inc. (previously cleared for carrier screening indications under K141410, and the same collection kit used to generate performance data for DEN140044, DEN160026, DEN170046, K182784, DEN180028, and K193492, which consists of a sealable collection tube containing a stabilizing buffer solution. Once the sample is collected, it is shipped to one of our Clinical Laboratory Improvement Amendments (CLIA) certified laboratories for testing. DNA is isolated from the saliva and tested in a multiplex assay using a customized genotyping beadchip, and off the shelf reagents and instrumentation manufactured by Illumina. The multiplex assay simultaneously tests for more than 500,000 variants, including those for the previously authorized indications, as well as for the indications proposed herein. Raw data is generated using Illumina GenomeStudio software, and then sent to 23andMe. The data is then analyzed using 23andMe's proprietary Coregen software, where a genotype is determined for each tested SNP. The results for certain of these SNPs are used to generate personalized reports for the customer that provide information about the detected genotype. Personalized reports are generated for each user that provide results of the testing performed. These reports tell the user which genetic health risk variant(s) have been detected in their sample and provide information about the disease associated with the variant(s). If no variant was detected, that information is also provided. The personalized reports are designed to present scientific concepts to users in an easy-to-understand format. The reports provide scientifically valid information about the risks associated with the presence of a particular variant. The reports are designed to help users understand the meaning of their results and any appropriate actions that may be taken based on their results. The modified components of the Personal Genome Service included in this 510(k) submission are new labeling to include (a) one new variant to be reported, and (b) the qualitative reporting of one's Genetic Health Risk for Hereditary Prostate Cancer (HOXB13-Related). Engineering drawings, schematics, etc. of Genetic Health Risk Report for Hereditary Prostate Cancer (HOXB13-Related) are not applicable to this device.

The 23andMe PGS Carrier Screening Test for Bloom Syndrome is indicated for the detection of the BLMAsh variant in the BLM gene from saliva collected using an FDA cleared collection device (Oragene DX model OGD-500.001). This test can be used to determine carrier status for Bloom syndrome in adults of reproductive age, but cannot determine if a person has two copies of the BLM140 variant. The test is most relevant for people of Ashkenazi Jewish descent.

The 23andMe Personal Genome Service (PGS) Carrier Screening Test for Bloom Syndrome (hereafter the "PGS") is a non-invasive genetic information service that combines qualitative genotyping data for an individual. The PGS is indicated for use for the detection of the BLM4sh variant in the BLM gene from saliva collected using the Oragene•Dx Saliva Collection Device (Oragene Dx model OGD-500.01). The core components of the PGS consist of the saliva collection kit: custom genotyping chip: laboratory procedures, equipment and analysis; and result reporting software.
