1Measurement precision
If DNA sequencing technology is used to perform genetic testing, then the cost of sequencing declines rapidly and genetic markers can be identified, but the complexity of multiple factors contributing to disease risk makes it difficult to accurately predict disease risk levels
Solution Approach 1:
The system segments the complex disease risk prediction problem into distinct components: genetic markers, family history, and environmental factors. Each component is processed separately through dedicated data collection modules, then integrated through machine learning algorithms to produce the final risk assessment. This segmentation allows each factor to be analyzed independently while maintaining overall system manageability.
Solution Approach 2:
The patent introduces machine learning algorithms as intermediaries between raw data inputs (genetic markers, family history, environmental factors) and the final disease risk prediction. These algorithms serve as mediators that automatically integrate multiple factors and compute risk levels, reducing the complexity burden on the system architecture while improving prediction accuracy through pattern recognition.
2Measurement precision
If multiple factors (genetic markers, family history, environmental factors) are integrated to predict disease risk, then prediction accuracy improves, but the complexity of data collection and processing increases
Solution Approach 1:
The system employs universal data collection modules that can handle multiple types of inputs (genetic data, family history, environmental factors) through standardized interfaces. The machine learning framework serves as a multi-functional engine that processes diverse data types using the same algorithmic structure, reducing overall system complexity while enabling comprehensive factor integration for accurate phenotype predictions.

AI summary
Databases and data processing systems for use with a network-based personal genetics services platform may include member information pertaining to a plurality of members of the network-based personal genetics services platform. The member information may include genetic information, family history information, environmental information, and phenotype information of the plurality of members. A data processing system may determine, based at least in part on the member information, a model for predicting a phenotype from genetic information, family history information, and environmental information, wherein determining the model includes training the model using the member information pertaining to a set of the plurality of members. The data processing system may also receive a request from a questing member to predict a phenotype of interest, and apply an individual's genetic information, family history information, and environmental information to the model to obtain a prediction associated with the phenotype of interest for the requesting member.
