Summary

Renal hypodysplasia/aplasia-4 (RHDA4) is characterized by bilateral renal agenesis, with severely reduced to absent amniotic fluid during pregnancy. Patients exhibit the Potter sequence, including flattened nose, ear anomalies, and receding chin, as well as limb contractures and joint dislocations in some patients (Arora et al., 2021; Al-Shamsi et al., 2022). For a general phenotypic description and discussion of genetic heterogeneity of renal hypoplasia/dysplasia, see RHDA1 (191830). [from OMIM]
