Shank3 mutation
SH3 and multiple ankyrin repeat domains 3 (Shank3), also known as proline-rich synapse-associated protein 2 (ProSAP2), is a protein that in humans is encoded by the SHANK3 gene on chromosome 22. Additional isoforms have been described for this gene but they have not yet been experimentally verified. WebbThe Shank3 gene encodes a multi-domain, scaffolding protein located at the postsynaptic density of excitatory synapses that interacts with a number of scaffolding and signaling proteins to form complexes that ensure proper synaptic formation and function ( Naisbitt et al., 1999; Tu et al., 1999; Ebert and Greenberg, 2013 ).

Webb30 dec. 2024 · Mutations affecting the synaptic-scaffold gene SHANK3 represent the most common genetic causes of autism with intellectual disability, accounting for about 1-2% of cases. Rare variants of this gene have also been associated with schizophrenia, and its deletion results in the autistic condition known as Phelan–McDermid syndrome. WebbWhile heterozygous SHANK3 mutations are usually the types of mutations associated with idiopathic autism in patients, heterozygous deletion of …
Webb7 juni 2024 · Shank3 mutation in the PFC-BLA neural circuit To precisely observe a gene mutation effect on a neural circuit, a methodology enabling a selective gene mutation within a specific circuit is needed. Thus, we developed an advanced circuit-specific Cre-expressing system by innovating our previous strategy ( Kim et al., 2024 ). Webb10 okt. 2024 · Shank3, an abundant excitatory postsynaptic scaffolding protein, has been associated with multiple brain disorders, including autism spectrum disorders (ASD) and Phelan-McDermid syndrome (PMS). However, how cell type-specific Shank3 deletion affects disease-related neuronal and brain functions remains largely unclear.
WebbAim 1: Generation of SHANK3 mutant and control human pluripotent stem cells. a. We will introduce the 3680Gins point mutation into SHANK3 using TALEN-mediated gene editing in established human ES lines. Our goal is to generate isogenic pairs of mutant and control cells that differ exclusively at the disease-causing mutation.
