Trait: luminal B breast carcinoma

Trait Information
Identifier MONDO_0021115
Description A biologic subset of breast carcinoma defined by low to moderate expression of genes characteristic of luminal epithelial cells including estrogen receptor (ER), and high expression of GGH, LAPTM4B, and CCNE1. This subtype of breast cancer is associated with a good prognosis, although not as favorable as the luminal A subtype. [NCIT: C53555]

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.
