Abstract: Objective To search for characteristic markers for neonatal screening in FGFR2-related diseases by applying a corpus callosum morphological evaluation model.Methods The morphological modeling included 2D thickness measurements of each part and computer-aided analysis of 3D virtural corpus callosum.Results Six neonates with FGFR2 gene pathogenic mutation or suspected pathogenic mutation in neonatal genome project were enrolled and all of them had different degrees of special facial features and abnormal cranial morphology. Four of them underwent corpus callosum morphological evaluation, of whom 3 were diagnosed as abnormal by MRI and cranial ultrasonography and 1 of them undergoing only cranial ultrasonography was also diagnosed as abnormal.Conclusion The application of corpus callosum morphologic evaluation in FGFR2-related diseases is expected to identify the potential marker phenotype which could be used in perinatal screening.
