    Abstract:
    Our study was designed to analyze prenatal manifestations in patients affected with cardio-facio-cutaneous syndrome (CFCS), in order to define indications of DNA testing in utero. Prenatal features were extracted from a national database and additional data were collected from 16 families contacted through the French association of CFC-Costello syndrome. We collected results of ultrasound scan (USS) biometrics, presence of congenital birth defects, and polyhydramnios. From the database, increased nuchal translucency was present in 13% of pregnancies, polyhydramnios in 52%, macrosomia and/or macrocephaly in 16%. Of the 16 pregnancies, 81% were complicated by abnormal USS findings. Polyhydramnios was reported in 67%. Head circumference, biparietal diameter, and abdominal circumference were above the 90th centile in 72%, 83% and, 81% of fetuses, respectively. Contrasting with macrosomia, femur length was below the 10th centile in 38%. Urinary tract abnormalities were found in 47% of fetuses. Most CFCS fetuses showed a combination of macrocephaly, macrosomia, and polyhydramnios, contrasting with relatively short femora. This growth pattern is also seen in Costello syndrome. We suggest that screening for CFCS and Costello gene mutations could be proposed in pregnancies showing this unusual pattern of growth parameters.
