PGK1 and B-cell chronic lymphocytic leukemia: For example, the expression level of the large tumor suppressor kinase 2 (LATS2) gene, after standardizing with the glyceraldehyde-3-phosphate dehydrogenase (GAPD) and phosphoglycerate kinase 1 (PGK1) gene expression levels, was 2.6-fold to 2.8-fold lower in CLL cases with Type I deletions compared to those with Type II deletions.
