Abstrakt: The article presents a case study of two patients with Simpson-Golabi-Behmel syndrome (SGBS) caused by the loss of-function of the glypican-3 gene (GPC3) and which showed Xq26.2 duplication. It informs about the tandem duplication of GPC3 identified by array comparative genomic hybridization (array-CGH). It also recommends a molecular transcription analysis to assess a possible gene disruption.
