Mutations in CDH1 encoding the E-cadherin were previously reported in hereditary diffuse gastric cancer as well as in nonsyndromic cleft lip/palate. Mutations in CTNND1 have never been reported before. The encoded protein, p120ctn, prevents E-cadherin endocytosis and stabilizes its localization at the cell surface. Conditional deletion of Cdh1 and Ctnnd1 in various animal models induces features reminiscent of BCD syndrome and underlines critical role of the E-cadherin-p120ctn interaction in eyelid, craniofacial, and tooth development. Our data assert BCD syndrome as a CDH1 pathway-related disorder due to mutations in CDH1 and CTNND1 and widen the phenotypic spectrum of E-cadherin anomalies.Genet Med advance online publication 09 March 2017.

Regardless of their extent, MFD that covered at least 25% of the placenta was almost always accompanied by severe growth restriction and by a high risk of intrauterine fetal death. Moreover, severe MFD tend to be associated with autoimmune diseases of the mothers, and pregnancies show more often a pathologic Doppler of the umbilical arteries and more often intrauterine fetal death that the moderate form. © 2017 John Wiley & Sons, Ltd.
