Although it is well known that RET mutation causes multiple endocrine neoplasia type 2A (MEN2A), thus far only 3 individuals have been reported to have MEN2A and renal agenesis/dysgenesis.
These results suggest that genomic alteration of RET or GDNF is not a major mechanism leading to renal agenesis and other severe kidney development defects.
These results demonstrate that mutations of ITGA8 are a genetic cause of bilateral renal agenesis and that, at least in some cases, bilateral renal agenesis is an autosomal-recessive disease.

Whole-exome sequencing identifies a GREB1L variant in a three-generation family with Müllerian and renal agenesis: a novel candidate gene in Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome. A case report.
Finally, we identified variants in novel candidate genes that were associated with perinatal lethality, including de novo mutations in GREB1L in two cases with bilateral renal agenesis, which represents a significant enrichment of such mutations in our cohort.
Mutations in genes encoding Fras1, Frem1 and Frem2 are causative for dermal-epidermal detachment in the plane of sublamina densa and have been identified in different classes of mouse bleb mutants, the murine model of human Fraser syndrome, the hallmark phenotypic characteristics of which are embryonic skin blistering, cryptophthalmos and renal agenesis.
The phenotype of renal agenesis/dysgenesis strongly indicates the existence of KAL1 gene defects in the genotype of patients with sporadic KS, providing evidence for the X-linked mode of inheritance and offering the opportunity for genetic counseling.
A defective anosmin-1 molecule may also play a role in the development of synkinesia and renal agenesis, which are exclusively seen in the X-linked form of KS.
The high frequency of renal agenesis in this family, in the presence and absence of the KAL-1 mutation, suggests an autosomal dominant or X-linked gene which may independently or co-dependently contribute to renal agenesis.
