“…Interestingly, the non-chromosome 22 alterations detected in ON meningiomas, including chromosome 2, 10, 17 and 20 abnormalities (Table 2), were relatively uncommon in intracranial (29, 30, 47) meningiomas and in our Sph-Ob meningiomas. Candidate genes present in these regions, some of which encoding for known tumor suppressors, include EML4 , MSH2 (Ch 2p); RPRM , GALNT13 , KCNJ3 (Ch 2q) and PTEN (Ch10q) (15, 17, 28, 45). Conversely, recurrent alterations in loci previously suspected of participating in meningioma development and/or progression were absent in ON, including MUTYH , PRDX1 , FOXD2 , FOXE3 , PTCH2 , RAD54L (1p); CTGF , TREM30A , SESN1 (Ch 6q); and NDRG2 , TMEM30B (Ch 14q) (28, 43).…”

“…Abnormalities are listed sequentially by case number to the left of the respective chromosomes. Only cases with abnormalities are illustrated (2, 3, 5, 6, 7, 8, 10, 11, 13, 14, 16, 17, 19). Gains are illustrated in green, deletions in red and copy neutral loss of heterozygosity (LOH) in gray.…”

“…perdas em -1p, -6q, -10, -14q e -18q; e ganhos em +1q, +9q, +12q, +15q, +17q e +20q (20,21). Geralmente a perda da expressão de merlina é decorrente à pequenas inserções ou deleções e mutações, que mais frequentemente ocorrem nos 2/3 da extremidade 5' do NF2…”

“…A perda do braço curto do cromossomo 1 associada à gênese de meningioma atípico ou grau I, representa a segunda anomalia cromossômica mais comum observado neste tumor (LOMAS et al, 2001;LOPEZ-GINES et al, 2004;NUNES et al, 2005). As perdas e ganhos de regiões cromossômicas durante a progressão tumoral de meningiomas são, provavelmente, devido a defeitos de instabilidade cromossômica e citocinese durante a divisão celular, como seguem: i) as perdas -1p, -6q, -10, e -14q -18q; e ii) ganhos + 1q, 9q +, + 12q, 15q +, + 17q e 20q (DOMINGUES et al, 2014;HOLLAND et al, 2011). Análises comparativas de alta resolução de hibridização e mutação genômicas foram utilizados para caracterizar prospectivamente as alterações no número de cópias de DNA de 150 meningiomas.…”
