Deletions in the short arm of chromosome 12 are the rarest subtelomeric imbalances. Less than 20 patients have been reported to date, and their microdeletions were identified either by FISH or array-CGH without SNP data. Here, we report a patient with a 12p13.32pter mosaic deletion detected by chromosome microarray analysis with loss of heterozygosity (LOH) of the deleted segment in addition to the adjacent distal segment. LOH is indicative of a complex rearrangement, suggestive of mitotic microhomology-mediated break-induced replication.
AgradecimentosA Deus por ter me abençoado até aqui e ter feito grandes coisas por mim! À minha orientadora, Juliana Forte Mazzeu de Araújo, meu primeiro contato em Brasília, pela oportunidade, orientação e compreensão. Aos pacientes e suas famílias por gentilmente concordarem em participar deste estudo.As agencias de fomento à pesquisa por financiarem nossas pesquisas.Meu agradecimento.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
