"Pathogenic or likely pathogenic variants in non-FGFR genes were identified in 43 individuals with diagnostic yields of 14% and 15% in retrospective and prospective cohorts respectively. Variants were identified most frequently in TCF12 (N = 22) and EFNB1 (N = 8) typically in individuals with nonsyndromic coronal craniosynostosis or TWIST1-negative clinically suspected Saethre-Chotzen syndrome."xsd:string
