Trait: IGF-1 measurement

Experimental Factor Ontology (EFO) Information
Identifier EFO_0004627
  • Is the quantification of Insulin-like growth factor 1 (IGF-1), also called somatomedin C. IGF-1 is a hormone similar in molecular structure to insulin. It plays an important role in childhood growth and continues to have anabolic effects in adults. Levels of IGF-1 are known to increase in some cancers.

PGS Performance Metrics

Disclaimer: The performance metrics are displayed as reported by the source studies. It is important to note that metrics are not necessarily comparable with each other. For example, metrics depend on the sample characteristics (described by the PGS Catalog Sample Set [PSS] ID), phenotyping, and statistical modelling. Please refer to the source publication for additional guidance on performance.
