MCDs er viktige årsaker til intellektuelle handikap og utgjør 20-40% av stoff-resistent barndommen epilepsi1,2. Interesse i MCDs har økt dramatisk det siste tiåret som følge av to viktige faktorer. Først er forbedring i hjernen imaging (spesielt MRI), som tillater leger og forskere å visualisere mange hjerne misdannelser som tidligere ikke ble gjenkjent. Den andre er utviklingen av genetisk verktøy som har tillatt identifikasjon av mange romanen MCD forå...

Hjernebarken spiller en nøkkelrolle i kognitiv og intellektuelle og er involvert i følelsesmessige kontroll som læring og hukommelse. Det er derfor ikke overraskende at mange nevrologiske og psykiske sykdommer skyldes misdannelser av kortikale utvikling (MCD). Etiologien for MCD er komplisert siden begge ervervet og genetiske faktorer er involvert. Kumulative utbredelsen av genetisk betinget andelen MCD er om lag 2%, og de er spredt i de fleste tilfeller. For eksempel forekomsten av medfødt hjernen dysgenesis ble anslått for å være høyere enn 1% i den menneskelige befolkningen, og noen former for MCD er observert i mer enn 14% av pasientene med epilepsi og 40% av alvorlig eller vanskelige epilepsi1, 2.
Periventricular nodulær Heterotopia (PNH) er en av de vanligste MCDs og er forårsaket av unormal overføringen av neurons fra sonen ventrikkel (VZ) å utvikle hjernebarken. Svikt av neurons å overføre resultatene i klynger av heterotopic neurons langs veggene av lateral ventriklene som kan vanligvis bli visualisert bruker magnetisk resonans Imaging (MRI). Klinisk, anatomiske og tenkelig funksjonene i PNH er heterogene. Knuter kan variere fra små og ensidig til bilaterale og symmetrisk. Vanlig klinisk sekvele inkluderer epilepsi og intellektuelle funksjonshemninger3. Mutasjoner i genet Filamin A (eller FLNA), som kart i Xq28, ble funnet i 100% av familier med X-tilknyttet bilaterale PNH og 26% av sporadiske pasienter3,4. En sjelden, recessiv form av PNH forårsaket av mutasjoner i genet ARFGEF2 , som kart i 20q13, har blitt rapportert i to consanguineous familier5. Nylig har biallelic mutasjoner i gener som koder reseptor-ligand cadherin paret DCHS1 og FAT4 blitt identifisert i ni pasienter som lider av en multisystemic lidelse som inneholder PNH6. PNH har også vært forbundet med skjøre X syndrom7, Williams syndrom8, 22q11 microdeletion syndrom9, duplikasjoner på 5 p 1510, slettinger på 1 p 3611, 5q14.3-q1512, 6 p 2513 og 6q terminal sletting syndrom14,15,16,17,18,19, antyder at flere utløsende gener er spredt gjennom genomet. Imidlertid ca 74% av sporadiske PNH pasienter gjenstår genetisk grunnlag for å bli belyst17.
Klassisk genet kartlegging tilnærminger som matrise sammenlignende Genomic hybridisering (matrise-CGH) har vist seg for å være et kraftig verktøy for deteksjon av sub mikroskopiske kromosomavvik, men genomisk regionene identifisert ved hjelp av denne tilnærmingen er ofte store og inneholder mange gener.
Ankomsten av massiv parallelle sekvenser teknikker (dvs hele-Exome sekvenser (WES) og hele-Genome sekvensering (WGS)) har betydelig redusert både kostnadene og tiden det tar å sekvens en hele menneskelige exome eller genom. Likevel forblir tolkning av WES og WGS utfordrende i fleste tilfeller siden for hver pasient titalls til hundrevis (eller kanskje tusenvis, alt fra typen analyse) varianter komme ut av data filtrering.
For å fremskynde prosessen med å identifisere romanen MCD forårsaker gener, en ny systematisk strategi kombinere matrise-CGH, ble WES og i utero electroporation (IUE) screening av kandidat gener utformet. IUE kan selektivt deaktivere (eller overexpress) bestemte gener eller mutasjoner i gnager hjernen, slik at rask vurdering av deres engasjement i corticogenesis18,19. RNAi formidlet-knockdown eller overuttrykte en eller flere kandidat gener forventes å forårsake, når genet er tilknyttet sykdom utvikling, lokalisere feil i neuronal overføring og/eller modning. Ved identifisering av et gen som inaktivering (eller overuttrykte) gjengir fenotypen observert hos pasienter i gnagere, blir det en enestående kandidat for screening i sporadisk pasienter med MCD. Bruker denne tilnærmingen, viste vi nylig avgjørende bidrag av C6orf70 genet (også kjent som ERMARD) i PNH patogenesen hos pasienter harbouring 6q27 chromosomal slettinger16.

a novel strategy combining array-cgh, whole-exome sequencing and in utero electroporation in rodents to identify causative genes for brain malformations

Fødselsskader som involverer hjernebarken-også kjent som misdannelser av kortikale utvikling (MCD) – er viktige årsaker til intellektuelle handikap og utgjør 20-40% av stoff-resistent epilepsi i barndommen. Høyoppløselig hjernen imaging har tilrettelagt i vivo identifikasjon av en stor gruppe MCD fenotyper. Til tross for fremskritt i hjernen imaging, genomisk analyse og generering av dyr modeller mangler en grei arbeidsflyt til å systematisk prioritere kandidat gener og teste funksjonelle effekter av antatte mutasjoner. Du løser dette problemet, ble en eksperimentell strategi aktivere identifikasjonen av romanen forårsaker gener MCD utviklet og godkjent. Denne strategien er basert på identifiserende kandidat genomisk regioner eller gener via matrise-CGH eller hele-exome sekvensering og karakterisere virkningene av deres inaktivering eller overuttrykte spesifikke mutasjoner i utviklingen gnager hjernen via i utero electroporation. Dette førte til identifisering av C6orf70 genet, koding for en antatte vesicula protein, til patogenesen av periventricular nodulær heterotopia, en MCD skyldes defekt neuronal migrasjon.

Den eksperimentelle strategien utformet for å identifisere romanen MCD forårsaker gener er recapitulated i figur 1.
Ved å utføre matrise-CGH i en kohort av 155 pasienter med utviklingsmessige hjernen unormalt ulik kombinerer PNH (figur 2A), corpus callosum dysgenesis, colpocephaly, lillehjernen hypoplasia og polymicrogyria forbundet med epilepsi, ataksi og kognitiv svekkelse, vi identifisert...

A Novel Strategy Combining Array-CGH, Whole-exome Sequencing and In Utero Electroporation in Rodents to Identify Causative Genes for Brain Malformations

Periventricular nodulær heterotopia (PNH) er den vanligste formen av misdannelse i kortikale utvikling (MCD) i voksen alder, men sin genetisk grunnlag er ukjent i mest sporadiske tilfeller. Vi har nylig utviklet en strategi å identifisere roman kandidat gener for MCDs og direkte bekrefte deres forårsaker rolle i vivo.
