摘要

Craniofrontonasal syndrome (CNFS) is an X-linked disorder caused by mutations in theEFNB1gene in which, paradoxically, heterozygous females are more severely affected than hemizygous males. In this paper, the clinical and molecular studies of a female subject with CFNS are described. A novelde novoc.473T>C (p.M158T) mutation in exon 3 ofEFNB1was demonstrated in this patient. The M158 residue of the Ephrin-B1 protein is highly conserved between species. Our results expand the mutational spectrum exposed by CNFS.
