DNA methylation analysis in Kabuki syndrome: reclassification of germline KMT2D variants Background Kabuki syndrome (KS) is a rare multiple congenital anomaly/neurodevelopmental disorder caused by heterozygous inactivating variants or structural rearrangements in the KMT2D gene. Although KS is recognizable due to its distinctive facial features, di...

DNA Methylation Characteristics for Recognizing Mowat-Wilson Syndrome Background Mowat-Wilson syndrome (MOWS) is a rare neurodevelopmental disorder caused by heterozygous deletions or loss-of-function mutations in the ZEB2 gene. This gene encodes a transcription factor involved in neural development. Individuals with MOWS often present with moderat...

Heterozygous THBS2 Pathogenic Variants Cause Ehlers-Danlos Syndrome with Prominent Vascular Features in Humans and Mice Paper Background Ehlers-Danlos syndrome (EDS) is a group of connective tissue disorders caused by mutations in collagen and collagen-related genes. These disorders present in various forms and can be classified into 14 different t...

A Novel Autosomal Dominant Parkinsonism/Cerebellar Ataxia Syndrome Caused by Cysteinyl-tRNA Synthetase Mutation Background Recently, a Chinese research team discovered a new pathogenic gene for a rare neurodegenerative disease that presents as a combination of Parkinson’s disease and cerebellar ataxia symptoms, which does not fit the description of...

Research Report: The Connection Between Cortical Gene Expression and Neurodevelopmental Disorders Research Background The anatomical and functional organization of the human brain is the result of the coordinated expression of numerous genes. It has been found that the first principal component (c1) of cortical gene expression plays a significant r...
