摘要

De Barsy syndrome (DBS) is characterized by progeroid features, ophthalmological abnormalities, intrauterine growth retardation, and cutis laxa. Recently, PYCR1 mutations were identified in cutis laxa with progeroid features. Herein, we report on a DBS patient born to a nonconsanguineous Chinese family. The exceptional observation of congenital glaucoma, aortic root dilatation, and idiopathic hypertrophic pyloric stenosis in this patient widened the range of symptoms that have been noted in DBS. Mutation analysis of PYCR1 revealed compound heterozygous PYCR1 mutations, including a p.P115fsX7 null mutation allele and a second allele with two missense mutations in cis: p.G248E and p.G297R. The effect of mutation results in a reduction of PYCR1 mRNA expression and PYCR1 protein expression in skin fibroblasts from the patient. The findings presented here suggest a mutation screening of PYCR1 and cardiovascular survey in patients with DBS.
