In France, Kurg et al. also identified 53% of the prevalence of renal anomalies in BOR patients harboring EYA1 variants; there is a wide range of abnormalities, namely, renal hypoplasia, multicystic kidney dysplasia, agenesis, abnormal pyelo-ureteral junction, and kidney malrotation, to name the most common (Krug et al., 2011). The gene discussed is EYA1; the disease is renal hypoplasia.
