Both a frameshift and a missense mutation of the STRA6 gene observed in an infant with the Matthew-Wood syndrome

Birth Defects Res. 2017 Mar 1;109(4):251-253. doi: 10.1002/bdra.23465.

Abstract

Background: The Matthew-Wood syndrome is associated with mutations of the STRA6 gene. It combines a pulmonary agenesis/hypoplasia; microphthalmia/anophthalmia; congenital cardiac, digestive, and urogenital malformations; and diaphragmatic defects.

Case: A 23-year-old nulliparous woman was referred to our center after a fetal ultrasound examination at 26 weeks of pregnancy revealed an abnormal head shape, a heart malformation, multiple cysts in both kidneys, and dilated ureters. A male baby (46, XY; 3600g; Apgar score 1) was delivered at 38 weeks of gestation and died 1 hr later due to respiratory failure. The diagnosis of Matthew-Wood syndrome was suspected given the association of bilateral anophthalmia, agenesis of the left lung, and heart and kidney defects. It was confirmed by the identification of two deleterious mutations of the STRA6 gene.

Results: The child was a compound heterozygote for two previously reported mutations, a paternally inherited missense mutation (c.878C>T [p.Pro293Leu] and a maternally inherited frameshift mutation (c.50_52delACTinsCC [p. Asp17Alafs*55]), producing a premature stop codon.

Conclusion: The diagnosis of Matthew-Wood syndrome should be considered in all fetuses with microphthalmia/anophthalmia. It requires an extensive ultrasound/MRI examination of the lung, heart, and diaphragm. Birth Defects Research 109:251-253, 2017. © 2017 Wiley Periodicals, Inc.
