OBJECTIVE: To explore the genetic basis for a couple with recurrent conceptions of fetus with abnormal longbones, and another couple with a history of omphalocele. METHODS: Genomic DNA was extracted from the peripheral blood samples from both couples. All exons and flanking regions were analyzed with next generation sequencing. Candidate variants were verified by Sanger sequencing. RESULTS: Couple one was found to be heterozygous for, a c.997+1G>T splice-site variant and a missence c.871G>A(p.Glu291Lys) variant of the ALPL gene. Both variants were predicted to be pathogenic and may result in reduced function or loss of alkaline phosphatase. For couple two, the wife was found to harbor a novel c.637_652 delins CCC variant of the CDKN1C gene. This deletion-insertion variant resulted in frame-shift and loss of function (p.Ala213Profs*55) of the CDKN1C protein. Maternally inherited CDKN1C LOF variant has been found to underlie Beckwith-Wiedemann syndrome (BWS), which may manifest as omphalocele. CONCLUSION Dispite the lack the direct proof from the lost fetuses, the variants of ALPL and CDKN1C genes can explain the recurrence of fetal malformations for both couples.

Beckwith-Wiedemann sydrome is a multisystemic pattern of congenital anomalies with overgrowth. This syndrome is first described independently by Beckwith in 1963 and by Wiedemann in 1964. There is wide spectrum of clinical manifestations, including prenatal or postnatal overgrowth, neonatal hypoglycemia, macroglossia, visceromegaly, omphalocele, hemihypertrophy and a predisposition for embryonal tumors, most frequently Wilms' tumor. We experienced a case of Beckwith-Wiedemann syndrome who developed left adrenal cortical neoplasm of indeterminate malignant potential.

Placental mesenchymal dysplasia (PMD) is a rare placental disorder that may coexist with a normal fetus but is frequently associated with fetal growth restriction, fetal demise, prematurity, and Beckwith-Wiedemann syndrome, as well as with various fetal anatomical and vascular anomalies. In this case, ultrasonography performed at 14 weeks of gestation revealed multiple, variable sized cysts in the placenta along with a morphologically normal fetus. Serial sonographic examinations found that the fetus became small for gestational age and had a dysplastic right kidney. After delivery at 33 weeks of gestation, histopathologic examination of the placenta showed enlarged, hydropic stem villi with cavity formation and absence of trophoblastic proliferation and pseudoinclusions, all of which were consistent with PMD. Neonatal abdominal ultrasonography showed multiple cysts in the right kidney consistent with a multicystic dysplastic condition. This appears to be the first case of PMD associated with fetal multicystic dysplastic kidney.

Beckwith-Wiedemann syndrome consists of various abnormalities, including macroglossia, visceromegaly, omphalocele, and neonatal hypoglycemia. These abnormalities frequently require operative correction and careful anesthetic management. Principal problems associated with anesthetic management in this syndrome are congenital heart disease, hypoglycemia, and difficult airway combined with macroglossia. We report two cases of general anesthetic management in children with Beckwith-Wiedemann syndrome.
