Mutations in mediator of RNA polymerase II transcription subunit 12 homolog (MED12, OMIM 300188) cause X‐linked intellectual disability (XLID) disorders including FG, Lujan, and Ohdo syndromes. The Gli3‐dependent Sonic Hedgehog (SHH) signaling pathway has been implicated in the original FG syndrome and Lujan syndrome. How are SHH‐signaling defects related to the complex clinical phenotype of MED12‐associated XLID syndromes are not fully understood.
