Can clinical assessment detect 22q11.2 deletions in patients with cardiac malformations?
Clinical assessment identifies less than 3/4 patients with a 22q11.2 deletion, whereas more than 1/4 remain undiagnosed if genetic tests are not performed on a routine basis. In this review, we found that clinical assessment is not suited for detecting individuals to be tested for 22q11.2 deletions.
Increased ASS-1 expression by these cells, in order to increase L-arginine concentration, is inadequate, suggesting a mechanism by which arginine depletion can be used in multimodality therapy for arginine-dependent cancers.
