Introduction: Congenital disorders of glycosylation (CDG) are autosomal recessive hereditary genetic disorders characterized by abnormal glycosylation of N-linked oligosaccharides.

Case Presentation: In this research, prenatal testing (24th week of pregnancy) revealed findings like polyhydramnios, hydrocephaly, abnormal facial features/shape, brain morphology abnormality, spina bifida, vertebral column abnormality, macrocephaly, scoliosis, micrognathia, abnormal kidney morphology, short fetal femur length, and short fetal humerus length in the fetus. Whole-exome sequencing was performed; the gene has shown a pathogenic variant.

Discussion: Homozygous patients have never been seen before in the literature for COG5-CDG. We demonstrate the first CDG patient at fetus stage with homozygous c.95T>G variant.

JAGN1 (Jagunal-homolog1) is a ER-resident transmembrane protein which is part of the early secretory pathway and granulocyte colony-stimulating factor receptor mediated signaling. Autosomal recessively inherited variants in the JAGN1 gene lead to congenital neutropenia, early-onset bacterial infections, aphthosis and skin abscesses due to aberrant differentiation and maturation of neutrophils. In addition, bone metabolism disorders and a syndromic phenotype, including facial features, short stature and neurodevelopmental delay, have been reported in affected patients.

Novel denovo variants of exome sequences are major cause of pathogenic neurodevelopmental disorders with a dominant genetic mechanism that emphasize their heterogeneity and complex phenotypes. White Sutton syndrome and Gabriele-de-Vries syndrome are congenital neuro-impairments with overlap of severe intellectual disability, microcephaly, convulsions, seizures, delayed development, dysmorphism of faces, retinal diseases, movement disorders and autistic traits. POGZ gene codes for pogo transposable element-derived zinc-finger protein and YY1 gene regulates transcription, chromatin, and RNA-binding proteins that have been associated with White Sutton and Gabriele-de-Vries syndromes, in recent data.

We present the case of a 51-year-old man with Von Hippel-Lindau disease and a history of renal transplantation who developed a persistent, painful tongue lesion with episodes of significant swelling. Given his history of prolonged immunosuppression and elevated cancer risk, oral squamous cell carcinoma was a major concern. However, histopathological evaluation confirmed recrudescent herpes simplex virus (HSV) infection rather than malignancy.

Hypoplastic left heart syndrome (HLHS) is a severe congenital heart disease associated with microcephaly and poor neurodevelopmental outcomes. Here we show that the Ohia HLHS mouse model, with mutations in Sap130, a chromatin modifier, and Pcdha9, a cell adhesion protein, also exhibits microcephaly associated with mitotic block and increased apoptosis leading to impaired cortical neurogenesis. Transcriptome profiling, DNA methylation, and Sap130 ChIPseq analyses all demonstrate dysregulation of genes associated with autism and cognitive impairment.

Background: Orofacial clefts are the most common craniofacial anomalies that include a variety of conditions affecting the lips and oral cavity. They remain a significant global public health challenge. Despite this, the quality of care for orofacial clefts has not been investigated at global and country levels.
