Abstract
The ventral body wall (VBW) that encloses the thoracic and abdominal cavities arises by extensive cell movements and morphogenetic changes during embryonic development. These morphogenetic processes include embryonic folding generating the primary body wall; the initial ventral cover of the embryo, followed by directed mesodermal cell migrations, contributing to the secondary body wall. Clinical anomalies in VBW development affect approximately 1 in 3000 live births. However, the cell interactions and critical cellular behaviors that control VBW development remain little understood. Here, we describe the embryonic origins of the VBW, the cellular and morphogenetic processes, and key genes, that are essential for VBW development. We also provide a clinical overview of VBW anomalies, together with environmental and genetic influences, and discuss the insight gained from over 70 mouse models that exhibit VBW defects, and their relevance, with respect to human pathology. In doing so we propose a phenotypic framework for researchers in the field which takes into account the clinical picture. We also highlight cases where there is a current paucity of mouse models for particular clinical defects and key gaps in knowledge about embryonic VBW development that need to be addressed to further understand mechanisms of human VBW pathologies.

Abstract
Very few cases of craniorachischisis (CRN) with concomitant omphalocele (OMP) in the setting of trisomy 18 are reported in literature. Solitary midline closure defects are estimated to be more prevalent in trisomy 18 compared to the general population. Neurulation defect comparisons include anencephaly 0-2% versus 0.0206%, spina bifida 1-3% versus 0.0350%, and encephalocele 0-2% versus 0.0082% [Parker et al. (2010); Birth Defects Research. Part A: Clinical and Molecular Teratology, 88:1008-1016; Springett et al. (2015); American Journal of Medical Genetics. Part A, 167A:3062-3069]. The solitary anterior malformation OMP has been reported as high as 6% with trisomy 18 [Springett et al. (2015); American Journal of Medical Genetics. Part A, 167A:3062-3069]. We report the third published case of CRN with concomitant OMP observed in a likely trisomy 18 fetus that screened positive by noninvasive prenatal screening. Furthermore, we review and analyze the current literature to augment understanding of the genetic basis for anterior and posterior closure defects such as CRN and OMP. Although the current genetic lexicon lacks any definitive association with the simultaneous defects presented, previous research elucidated various genes related to anterior or posterior closure interruption individually. By consolidating current research, the authors advance knowledge of interconnected genetic pathology and direct future genetic mapping efforts.

Genome-wide association study reveals a QTL and strong candidate genes for umbilical hernia in pigs on SSC14. BMC Genomics 2018; 19:412. [PMID: 29843603 PMCID: PMC5975507 DOI: 10.1186/s12864-018-4812-9] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2017] [Accepted: 05/22/2018] [Indexed: 11/22/2022] Open
Abstract
Background Umbilical hernia is one of the most prevalent congenital defect in pigs, causing economic losses and substantial animal welfare problems. Identification and implementation of genomic regions controlling umbilical hernia in breeding is of great interest to reduce incidences of hernia in commercial pig production. The aim of this study was to identify such regions and possibly identify causative variation affecting umbilical hernia in pigs. A case/control material consisting of 739 Norwegian Landrace pigs was collected and applied in a GWAS study with a genome-wide distributed panel of 60 K SNPs. Additionally candidate genes were sequenced to detect additional polymorphisms that were used for single SNP and haplotype association analyses in 453 of the pigs. Results The GWAS in this report detected a highly significant region affecting umbilical hernia around 50 Mb on SSC14 (P < 0.0001) explaining up to 8.6% of the phenotypic variance of the trait. The region is rather broad and includes 62 significant SNPs in high linkage disequilibrium with each other. Targeted sequencing of candidate genes within the region revealed polymorphisms within the Leukemia inhibitory factor (LIF) and Oncostatin M (OSM) that were significantly associated with umbilical hernia (P < 0.001). Conclusions A highly significant QTL for umbilical hernia in Norwegian Landrace pigs was detected around 50 Mb on SSC14. Resequencing of candidate genes within the region revealed SNPs within LIF and OSM highly associated with the trait. However, because of extended LD within the region, studies in other populations and functional studies are needed to determine whether these variants are causal or not. Still without this knowledge, SNPs within the region can be used as genetic markers to reduce incidences of umbilical hernia in Norwegian Landrace pigs.

Abstract
Background Omphalocele is a congenital midline ventral body wall defect that can exist as isolated malformation or as part of a syndrome. It can be considered one of the major and most frequent clinical manifestation of Beckwith-Wiedemann Syndrome (BWS) in case of loss of methylation at KCNQ1OT1: Transcription Star Site-Differentially Methylated Region (TSS-DMR) or in presence of CDKN1C mutations. The isolated form of the omphalocele accounts approximately for about the 14% of the total cases and its molecular etiology has never been fully elucidated. Methods Given the tight relationship with BWS, we hypothesized that the isolated form of the omphalocele could belong to the heterogeneous spectrum of the BWS associated features, representing an endophenotype with a clear genetic connection. We therefore investigated genetic and epigenetic changes affecting BWS imprinted locus at 11p15.5 imprinted region, focusing in particular on the KCNQ1OT1:TSS DMR. Results We studied 21 cases of isolated omphalocele detected during pregnancy or at birth and identified the following rare maternally inherited variants: i) the non-coding variant G > A at nucleotide 687 (NR_002728.3) at KCNQ1OT1:TSS-DMR, which alters the methylation pattern of the imprinted allele, in one patient; ii) the deletion c.624-629delGGCCCC at exon 1 of CDKN1C, with unknown clinical significance, in two unrelated cases. Conclusions Taken together, these findings suggest that KCNQ1OT1:TSS-DMR could be a susceptibility locus for the isolated omphalocele.

Abstract
Umbilical hernia (UH) is one of the most common congenital defects in pigs, leading to considerable economic loss and serious animal welfare problems. To test whether copy number variations (CNVs) contribute to pig UH, we performed a case-control genome-wide CNV association study on 905 pigs from the Duroc, Landrace and Yorkshire breeds using the Porcine SNP60 BeadChip and penncnv algorithm. We first constructed a genomic map comprising 6193 CNVs that pertain to 737 CNV regions. Then, we identified eight CNVs significantly associated with the risk for UH in the three pig breeds. Six of seven significantly associated CNVs were validated using quantitative real-time PCR. Notably, a rare CNV (CNV14:13030843-13059455) encompassing the NUGGC gene was strongly associated with UH (permutation-corrected P = 0.0015) in Duroc pigs. This CNV occurred exclusively in seven Duroc UH-affected individuals. SNPs surrounding the CNV did not show association signals, indicating that rare CNVs may play an important role in complex pig diseases such as UH. The NUGGC gene has been implicated in human omphalocele and inguinal hernia. Our finding supports that CNVs, including the NUGGC CNV, contribute to the pathogenesis of pig UH.

Abstract
OBJECTIVE We successfully employed silver-impregnated hydrofiber dressing for management of giant omphaloceles (GO) followed by delayed surgical closure. STUDY DESIGN Between 2005 and 2008, eight consecutive GO infants were cared for at Driscoll Children's Hospital. Four patients had additional congenital anomalies including Beckwith-Wiedemann (n = 1), tetralogy of Fallot (n = 1), pulmonary hypoplasia (n = 1), and ruptured omphalocele (n=1). Infants underwent amnion epithelization using a silver-impregnated hydrofiber dressing over the course of several months followed by delayed surgical closure. Mean ± SD of parameters including maternal age, gestational age, infant weight, size of GO, preoperative intubation, preoperative hospitalization, time to epithelization, days to surgical closure, postoperative hospitalization, postoperative intubation and months of follow-up were studied. RESULTS Five patients underwent successful closure, 2 were lost to follow-up and 1 was lost because of withdrawal of support. The maternal age, gestation age and weight of infant were 28 ± 5.3 years, 34 ± 4 weeks and 2.5 ± 0.62 kg, respectively. The GO size was 11 cm in length and 11 cm in width, respectively. Preoperative hospitalization days were 78 ± 74 days. Preoperative intubation was 3.5 ± 3.1 days with 2 neonates requiring tracheostomy and home ventilation owing to additional congenital abnormalities. Time to epithelization was 2.9 ± 0.9 months. Days to surgical closure and postoperative hospitalization were 331 ± 119 days and 5 ± 3.4 days, respectively. Average follow-up was 37 ± 27 months. No treatment associated morbidities are noted. CONCLUSIONS Silver-impregnated hydrofiber mediated epithelization of GO followed by delayed surgical closure is safe for management of infants.
