Because in humans GCM2 downregulation and mutations are associated with parathyroid adenomas and hypoparathyroidism, respectively (Mannstadt et al. 2008; Doyle et al. 2012; Yi et al. 2012; Park et al. 2013; Mitsui et al. 2014), while GCM1 downregulation is associated with preeclampsia (Chen et al. 2004), the downstream genes identified in this work, including TBX1, GATA factors, and FGFR, represent interesting candidates to dissect the molecular mechanisms underlying these pathologies. Here, GCM2 is linked to hypoparathyroidism.
