H6PD and endometrioid adenocarcinoma: Exome sequencing of the right endometrioid carcinoma revealed a pathogenic mutation of hexose-6-phosphate dehydrogenase/glucose 1-dehydrogenase (H6PD), TFAP2D, MYO7A, TGM1, SEMA6B, ZNF99, and SIGLEC1. Loss of heterozygosity (LOH) in the 10q.23.3 (PTEN) locus was not recognized by copy number variation analysis in this tumor DNA.
