The most common known molecular defect in Wilms tumor (WT) of the kidney, the most frequent solid tumor of childhood, is loss of imprinting (LOI) of the insulin-like growth factor-II gene (IGF2), which involves activation of the normally silent maternal allele of the gene and hypermethylation of a differentially methylated region upstream of the H19 gene.

We demonstrate that SNP arrays are of real diagnostic interest in Beckwith-Wiedemann syndrome: 1) they help to distinguish patUPDs from trisomies more precisely than karyotyping and FISH, 2) they help determine the size and mosaicism rate of patUPDs, 3) they provide complementary information in inconclusive cases, helping to distinguish low-rate patUPD mosaicism from other BWS-related molecular defects.
