SYNGAP1 is a gene associated with autism spectrum disorder and intellectual disabilities. In this work I analysed two scientific papers that study the impact of Syngap1 mutation in zebrafish, obtained with two different approaches of genetic interference, that is morpholino oligonucleotides and CRISPR/Cas9. The resulting modifications confirmed that the gene is fundamental for the early phases of embryological brain development, but also for spontaneous and stimulus-associated behavior in later developmental phases. Both works confirm that Syngap1 haploinsufficiencies generate stereotyped behavior, unproductive escape responses, context-dependent hyperactivity. This work aims at confronting the methods by which mutants and morphants were obtained and the associated results.
SYNGAP1 è un gene associato allo spettro autistico e a disabilità intellettive. In questo elaborato ho analizzato due articoli scientifici che studiano l'impatto della mutazione di Syngap1 in zebrafish utilizzando due approcci alternativi di interferenza genica, ovvero morfolino oligonucleotidi e CRISPR/Cas9. Le modifiche ottenute hanno confermato che il gene è fondamentale nelle prime fasi di sviluppo embrionale del cervello, ma anche nei comportamenti spontanei e associati a stimoli sensoriali degli esemplari nelle fasi successive dello sviluppo. Entrambi i lavori confermano che aploinsufficienze di Syngap1 causano comportamenti stereotipati, risposte di fuga improduttive, iperattività contesto-dipendente. Questo lavoro si propone di confrontare i metodi di ottenimento dei mutanti e dei morfanti, e i risultati a essi associati.

Abstract
SYNGAP1 is a gene associated with autism spectrum disorder and intellectual disabilities. In this work I analysed two scientific papers that study the impact of Syngap1 mutation in zebrafish, obtained with two different approaches of genetic interference, that is morpholino oligonucleotides and CRISPR/Cas9. The resulting modifications confirmed that the gene is fundamental for the early phases of embryological brain development, but also for spontaneous and stimulus-associated behavior in later developmental phases. Both works confirm that Syngap1 haploinsufficiencies generate stereotyped behavior, unproductive escape responses, context-dependent hyperactivity. This work aims at confronting the methods by which mutants and morphants were obtained and the associated results.File | Dimensione | Formato | |
