A Case of Beare-Stevenson Cutis gyrata Syndrome Confirmed by Mutation Analysis of the Fibroblast Growth Factor Receptor 2 Gene

Abstract

This paper reports a case of Beare-Stevenson cutis gyrata syndrome confirmed by DNA analysis of the patient's fibroblast growth factor receptor (FGFR) genes. At birth, the patient had ocular proptosis, a red nevus with skin tags on her forehead and an umbilical stump. She developed craniosynostosis, craniofacial dysmorphism and hydrocephalus. Her treatment included forehead and facial advancement and a ventriculoperitoneal shunt. Analysis of the FGFR genes revealed that she was heterozygous for a missense mutation in exon 10 for the FGFR2 protein, resulting in an amino acid substitution of cysteine for tyrosine at residue 375 (Tyr375Cys). This is the fourth case of Beare-Stevenson cutis gyrata syndrome confirmed by mutation analysis of the FGFR genes.
