Genetic analysis performed looking at ciliopathies-associated genes was negative, but when the analysis was extended to the entire panel of genes associated with monogenic renal diseases, a variant in CDKN1C gene (#600,856) was found, a gene associated with Beckwith-Wiedemann syndrome with autosomal dominant transmission (https://omim.org/entry/130650). This evidence concerns the gene CDKN1C and Beckwith-Wiedemann syndrome.
