The FGFR3 variations in Cases 9, 24, and 25 were recurrent and shown to be causative for achondroplasia (ACH, #100800) (Heuertz et al. 2006), thanatophoric dysplasia type I (TD I, #187600) (Xue et al. 2014), and ACH (Foldynova‐Trantirkova, Wilcox, and Krejci 2012), respectively. The gene discussed is FGFR3; the disease is thanatophoric dysplasia type 1.
