Abstract
Spina Bifida (SB) and Wilm's Tumor (WT) are conditions, both associated with children. Several studies have shown that WT later develops in SB patients, which led us to elucidate common key genes and linked pathways of both conditions, aimed at their concurrent therapeutic management. For this, integrated bioinformatics analysis was employed. A comprehensive manual curation of genes identified 133 and 139 genes associated with SB and WT, respectively, which were used to construct a single protein-protein interaction (PPI) network. Topological parameters analysis of the network showed its scale-free and hierarchical nature. Centrality-based analysis of the network identified 116 hubs, of which, 6 were called the key genes attributed to being common between SB and WT besides being the hubs. Gene enrichment analysis of the 5 most essential modules, identified important biological processes and pathways possibly linking SB to WT. Additionally, miRNA-key gene-transcription factor (TF) regulatory network elucidated a few important miRNAs and TFs that regulate our key genes. In closing, we put forward TP53, DICER1, NCAM1, PAX3, PTCH1, MTHFR; hsa-mir-107, hsa-mir-137, hsa-mir-122, hsa-let-7d; and YY1, SOX4, MYC, STAT3; key genes, miRNAs and TFs, respectively, as the key regulators. Further, MD simulation studies of wild and Glu429Ala forms of MTHFR proteins showed that there is a slight change in MTHFR protein structure due to Glu429Ala polymorphism. We anticipate that the interplay of these three entities will be an interesting area of research to explore the regulatory mechanism of SB and WT and may serve as candidate target molecules to diagnose, monitor, and treat SB and WT, parallelly.Communicated by Ramaswamy H.

Abstract
Diaphanospondylodysostosis is an extremely rare, recessively inherited, perinatal lethal skeletal disorder associated with BMPER gene mutations. Clinically it is characterized by defects in costovertebral ossification, absent ribs, hypertelorism, short nose with depressed nasal bridge, low-set ears, and short neck. At the extraosseous level, the most frequent pathologic finding is nephroblastomatosis with multicystic kidneys. We present the case of a child of non-consanguineous parents who died at 2 months of age in our center. Autopsy showed a marked costovertebral ossification defect, perilobar nephrogenic rests and loss of white matter with periventricular leukomalacia. After genetic study, the diagnosis of diaphanospondylodysostosis was confirmed. A previously undescribed germinal mutation in the BMPER gene (c.576 + 2dupT) was found.

Abstract
Diaphonospondylodysotosis (DSD) and ischiospinal dysostosis (ISD) are rare skeletal dysplasias with variants in the bone morphogenetic protein-binding endothelial regulator (BMPER). There is a continuum of clinical presentation, with DSD at the severe end of the spectrum whilst ISD is towards the milder end. Both are caused due to pathogenic variants in BMPER. Previous studies have reported 20 patients from 13 families. Common features in the cohort reported so far are spinal and rib anomalies but other findings illustrate phenotypic variation. Survival ranges from death within the neonatal period to alive and well at 19 years. We present three siblings with variable phenotype, adding to the evidence for a single definition of BMPER-related skeletal dysplasia. We highlight the need for ongoing care planning and guarded prognostication, with regular review by clinical teams.

Abstract
Bone morphogenetic protein-binding endothelial cell precursor-derived regulator (BMPER) gene mutation presents a disease spectrum ranging from a mild type of ischiospinal dysostosis (ISD) to a more severe type of diaphanospondylodysostosis (DSD). It is known that BMPER gene mutations are very rare, and their resulting clinical manifestations, including musculoskeletal modifications, appear in a spectrum of various types and severity levels. With the development of genetic diagnosis, case reports of patients with specific mutations in the BMPER gene have been published. The most commonly known clinical features are kidney structural problems, including neuroblastoma and renal cysts. Meanwhile, respiratory failure is a common and fatal symptom for patients with BMPER gene mutation, but it does not appear to have been well evaluated or managed so far. We report a case of a confirmed novel mutation of c.1750delT (p.Cys584fs) in the BMPER gene in a female adolescent patient and highlight the importance of the regular assessment of respiratory failure for successful management of this condition.

Abstract
Background Diaphanospondylodysostosis (DSD) is a rare congenital, lethal skeletal disorder caused by recessively inherited mutations in the BMPER gene, which encodes the bone morphogenetic protein‐binding endothelial cell precursor‐derived regulator. The most prominent features of DSD are missing ossification of the axial skeleton, rib abnormalities and thoracic hypoplasia/insufficiency, as well as intralobar nephrogenic rests within the kidneys. Methods We report on the case of a 22‐month‐old patient with DSD where trio‐exome sequencing was performed. Results Genetic testing revealed a homozygous nonsense variant c.1577G>A (p.Trp526*) in the BMPER gene, leading to a premature stop in protein translation. Both parents are asymptomatic carriers for the BMPER variant, which has not been described in the literature before. Conclusions Our findings expand the genotypic and phenotypic spectrum of BMPER variants leading to DSD.

Abstract
Diaphanospondylodysostosis (DSD) is a rare autosomal recessive skeletal disorder, characterized mainly by ossification defects in vertebrae, thorax malformations, renal cystic dysplasia and usually death in the perinatal period. DSD is caused by mutations in the bone morphogenetic protein-binding endothelial regulator (BMPER) gene. We describe the prenatal findings of a non-consanguineous Jewish couple (shared Balkan origin), with three affected fetuses that presented with malformations in the spine and chest, reduced ossification of the skull and spine, horseshoe kidney and increased nuchal translucency. The unique combination of these ultrasound (US) features raised the possibility of DSD, which was confirmed by whole exome sequencing (WES) performed on a single fetal DNA and familial segregation. In the three fetuses, a novel homozygous mutation in BMPER (c.410T > A; p.Val137Asp) was found. This mutation, which segregated in the family, was not found in 65 controls of Jewish Balkan origin, and in several large databases. Taken together, the combination of a detailed prenatal US examination and WES may be highly effective in confirming the diagnosis of a rare genetic disease, in this case DSD.

Abstract
Ischiospinal dysostosis (ISD) is a polytopic dysostosis characterized by ischial hypoplasia, multiple segmental anomalies of the cervicothoracic spine, hypoplasia of the lumbrosacral spine and occasionally associated with nephroblastomatosis. ISD is similar to, but milder than the lethal/semilethal condition termed diaphanospondylodysostosis (DSD), which is associated with homozygous or compound heterozygous mutations of bone morphogenetic protein-binding endothelial regulator protein (BMPER) gene. Here we report for the first time biallelic BMPER mutations in two patients with ISD, neither of whom had renal abnormalities. Our data supports and further extends the phenotypic variability of BMPER-related skeletal disorders.
