JAMA Psychiatry<\/em><\/a> asseguren que aquests gens no predestinen a patir pensaments su\u00efcides, per\u00f2 si que podrien suposar un major risc, sobretot combinats amb esdeveniments vitals.<\/p>\nPer tal d\u2019identificar aquets marcadors gen\u00e8tics s\u2019ha analitzat tot el genoma de 633.778 militars veterans dels Estats Units. Entre ells casi el 20% havien patit pensaments o comportaments su\u00efcides que havien quedat registrats en el seu historial m\u00e8dic.<\/p>\n
Els investigadors van identificar quatre gens amb un vincle molt fort amb els comportaments su\u00efcides. En primer lloc el receptor d\u2019estr\u00f2gens<\/strong>, pr\u00e8viament identificat com a gen causal de depressi\u00f3 i del trastorn d\u2019estr\u00e8s posttraum\u00e0tic. En segon lloc, el receptor de la dopamina<\/strong>, relacionat amb intents de su\u00efcidi, esquizofr\u00e8nia o trastorns de l\u2019estat d\u2019\u00e0nim, entre d\u2019altres. En tercer lloc el gen DCC, expressat en el teixit cerebral i que ja ha estat associat a m\u00faltiples condicions psiqui\u00e0triques. I finalment, el TRAF3<\/strong>, que est\u00e0 relacionat amb el comportament antisocial, el consum de subst\u00e0ncies i el TDAH.<\/p>\n“Encara que els gens representen una petita part del risc en comparaci\u00f3 amb altres factors, necessitem comprendre millor les vies biol\u00f2giques subjacents a que una persona tingui un comportament su\u00efcida<\/em> –afirmen els investigadors-. El su\u00efcidi \u00e9s la quarta causa de mort entre les persones de 15 a 29 anys. Com m\u00e9s sapiguem, millor podrem prevenir aquestes tr\u00e0giques morts<\/em>\u201d.<\/p>\n <\/p>\n
