Abstract The 22q13.3 deletion syndrome results from loss of terminal segments varying sizes at 22qter. Few genotype–phenotype correlations have been found but all patients mental retardation and severe delay, or absence of, expressive speech. We carried out clinical molecular characterization 13 patients. Developmental delay speech abnormalities were common to comparable in frequency severity previously reported cases. Array‐based comparative genomic hybridization showed the deletions vary...
Cell lineages of the early human gonad commit to one two mutually antagonistic organogenetic fates, testis or ovary. Some individuals with a 46,XX karyotype develop testes ovotestes (testicular ovotesticular disorder sex development; TDSD/OTDSD), due presence testis-determining gene, SRY Other rare complex syndromic forms TDSD/OTDSD are associated mutations in pro-ovarian genes that repress development (e.g. WNT4); however, genetic cause more common non-syndromic is unknown. Steroidogenic...
ATP synthase, H+ transporting, mitochondrial F1 complex, δ subunit (ATP5F1D; formerly ATP5D) is a of synthase and plays an important role in coupling proton translocation production. Here, we describe two individuals, each with homozygous missense variants ATP5F1D, who presented episodic lethargy, metabolic acidosis, 3-methylglutaconic aciduria, hyperammonemia. Subject 1, for c.245C>T (p.Pro82Leu), recurrent decompensation starting the neonatal period, subject 2, c.317T>G (p.Val106Gly),...
SMARCC2 (BAF170) is one of the invariable core subunits ATP-dependent chromatin remodeling BAF (BRG1-associated factor) complex and plays a crucial role in embryogenesis corticogenesis. Pathogenic variants genes encoding other components have been associated with intellectual disability syndromes. Despite its significant biological role, not directly human disease previously. Using whole-exome sequencing web-based gene-matching program, we identified 15 individuals variable degrees...
Sonic hedgehog signaling regulates processes of embryonic development across multiple tissues, yet factors regulating context-specific Shh remain poorly understood. Exome sequencing families with polymicrogyria (disordered cortical folding) revealed individuals biallelic deleterious variants in TMEM161B , which encodes a multi-pass transmembrane protein unknown function. Tmem161b null mice demonstrated holoprosencephaly, craniofacial midline defects, eye and spinal cord patterning changes...
Abstract Sphingolipids are a diverse family of lipids with critical structural and signalling functions in the mammalian nervous system, where they abundant myelin membranes. Serine palmitoyltransferase, enzyme that catalyses rate-limiting reaction sphingolipid synthesis, is composed multiple subunits including an activating subunit, SPTSSA. both essential cytotoxic their synthesis must therefore be tightly regulated. Key to homeostatic regulation ORMDL proteins bound serine...
Abstract Postsynaptic density (PSD) proteins have been implicated in the pathophysiology of neurodevelopmental and psychiatric disorders. Here, we present detailed clinical genetic data for 20 patients with likely gene-disrupting mutations TANC2 —whose protein product interacts multiple PSD proteins. Pediatric disruptive autism, intellectual disability, delayed language motor development. In addition to a variable degree epilepsy facial dysmorphism, observe pattern more complex dysfunction...
