3. Gene dosage troubles and failure of testicular formation. When one is not enough! In this section, we will analyze the main known components (genes and loci) of the testis developmental pathway and will stress the fact that almost all steps are dosage-sensitive (Table 1). It is also to note that in most cases, mutations are responsible for a syndromic GD (complete or partial), that is to say, failure of testicular development comes accompanied with multiple abnormalities. This is to ...
