Recently, recessive loss-of-function mutations of IL11RA, encoding IL-11RA, were identified in patients with craniosynostosis and dental anomalies (CRSDA; Online Mendelian Inheritance in Man accession no. 614188; Nieminen et al., 2011; Keupp et al., 2013; Papachristoforou et al., 2013; Miller et al., 2017). Here, IL11RA is linked to craniosynostosis.
