Moreover, four patients (P1–3 and P5) had symptoms compatible with NPHP1 ciliopathy related CKD such as “reins discrètement hyperéchogènes” (mildly hyperechogenic kidneys), “infléchissement staturo-pondéral” (growth faltering) or “syndrome polyuro-polydipsique” (polyuro-polydipsia syndrome), that the UMLS-based extraction module of Dr. Warehouse failed to extract, because the expression used in the documents did not exist in the UMLS. This evidence concerns the gene NPHP1 and chronic kidney disease.
