PCDHGC3 and Sotos syndrome: Across all three syndromes there were 49 genes overlapping some DMR called by DMRscaler. Among these were PCDHGA1, PCDHGA2, PCDHGA3, PCDHGA8, PCDHGA10, PCDHGB7, PCDHGA11, PCDHGA12, and PCDHGC3 of the PCDHG cluster genes, previously discussed in context of Sotos syndrome alone.
