Synaptic Ras GTPase-activating protein 1 regulatory RNA (SYNGAP1 regulatory RNA)

SYNGAP1 regulatory RNA refers to non-coding RNA transcripts, such as natural antisense transcripts (NATs) or specific regulatory sequences within the SYNGAP1 pre-mRNA, that modulate the expression of the SYNGAP1 gene. The SYNGAP1 gene encodes a critical synaptic Ras GTPase-activating protein that is essential for proper synaptic plasticity, excitatory-inhibitory balance, and cognitive development. Mutations in one allele of SYNGAP1 lead to haploinsufficiency, resulting in SYNGAP1-related intellectual disability, epilepsy, and autism spectrum disorders. Therapeutic strategies, particularly antisense oligonucleotides (ASOs), are designed to bind these regulatory RNAs to enhance the translation or stability of SYNGAP1 mRNA. By inhibiting the repressive effects of these regulatory RNAs, these therapies aim to restore SYNGAP1 protein levels to near-physiological ranges, potentially mitigating the neurodevelopmental deficits associated with the disorder.

Antisense oligonucleotides (ASOs) target the SYNGAP1 regulatory RNA or specific pre-mRNA sequences to prevent the degradation of SYNGAP1 transcripts or to inhibit natural antisense-mediated repression, thereby increasing the production of functional SYNGAP1 protein from the remaining healthy allele in haploinsufficient patients.
