Abstract: Provided are compositions, including products of manufacture and kits, and methods, for predicting the successful construction of a genomic T-Cell Receptor (TCR) library from a tissue sample; or predicting the successful sequencing of a TCR sequence from a tissue sample, wherein optionally the tissue sample comprises or is derived from a biopsy or a Formalin-Fixation and Paraffin Embedding (FFPE) sample, and optionally the tissue sample is a human or an animal sample. In alternative embodiments, provided herein are assays for predicting successful library construction and sequencing of a TCR chain. In alternative embodiments, the T cell is a tumor infiltrating lymphocyte (TIL). The results of methods provided herein can generate a prediction as to the success of assays used for quantifying T-cells and sequencing T-cell receptors, including any commercially available assay (e.g., ImmunoSeq, Adaptive Biotechnologies, Seattle, Wash.) to effectively assess TCR quantity and clonality.

Abstract: Methods are provided herein to determine if a subject is a candidate for treatment with an inhibitor of 3-hydroxy-3-methylglutaryl coenzyme A reductase (HMGCR). The method includes determining the presence of at least one polymorphism in the HMGCR gene in a sample from a subject. The presence of at least one polymorphism indicates that the subject is a candidate for treatment with a statin, for example to decrease risk of or treat cancer, cardiovascular disease, diabetes, obesity, inflammatory disease, or auto-immune disease.

Abstract: The present invention provides compositions and methods for research, diagnostic, drug screening, and therapeutic applications related to colorectal cancer and related conditions. In particular, the present invention provides genetic variations in or associated with one or more of the STK38L, GPR45, TGFBRAP1, PADI3, IBRDC1, and/or GRK5 genes as being associated with such conditions.
