Assistant Professor at the Department of Genetics and Evolutionary Biology, Institute of Biosciences, USP. Graduated in Biological Sciences by the University of São Paulo (1993), master's degree (1996) and doctorate (2001) in Genetics at USP. Post-doctorate developed at the Center for Studies on the Human Genome, Area of Human Genetics and Cytogenetics. Research interests: relationship between chromosomal rearrangements and phenotypes; genetics of intellectual disability; cancer predisposition; investigation of genetic and epigenetic mutations in pediatric cancer.

Most rare diseases have an underlying genetic cause for their condition. There are more than 7,000 rare diseases, ~80% of which are thought to have a genetic cause. The majority (50-75%) of rare diseases affect children, and many are severe multisystem disorders with a range of phenotypes. Although individually they are rare, collectively they are responsible for 35% of deaths in the firs…
The Human Genome Research Center (HGRC-CEPID I) was initiated in 2000 with the main goal of increasing our basic knowledge and diagnosis of prevalent genetic diseases in the Brazilian population. The HGRC concentrated largely on Mendelian disorders, mainly neuromuscular, craniofacial, and mental disability. The scope was expanded in 2005 by incorporating stem-cell research, both as a too…
The DNA sequence is now the main source of biological information at individual and population levels. Hundreds of thousands of human genomes were sequenced, but only a few were analyzed cytogenetically. Chromosomal alterations occur in a small percentage of all live newborns, usually causing diseases. However, with the advent of molecular cytogenetics and, more recently, second generatio…
Cancer is the main cause of death due to illness among children and adolescents in Brazil. Although approximately 80% of these patients survive over 5 years, this population is likely to suffer serious adverse effects because of the treatment received, like heart disease, lung problems, and subsequent tumors. Pediatric cancers present distinct biological profiles compared to adult tumors;…

About 1% of the world's population has intellectual disability (ID), a condition that results in an important socioeconomic impact. ID is characterized by reduced ability to understand new information, learn skills and develop basic activities autonomy. When other phenotypes occur simultaneously, ID is classified as syndromic, which is often monogenic in origin. There are still gaps in th…
Microcephaly and macrocephaly are pathological phenotypes mainly resulting from changes in cranial size/volume. These changes may be a consequence of environmental factors, such as intrauterine or congenital infections, teratogenic exposures or vascular injuries, as well as driven by genetic causes, which include mutations in single genes, copy number variations (CNVs), and major structur…
Pediatric cancer presents a low incidence when compared to the cancer that develops in adults, presenting great differences regarding its biology and the causes that lead to its emergence, as the smaller involvement of environmental risk factors and short temporal window for its development. Hepatoblastoma is an embryonic liver tumor that develops in the first years of life, with liver ca…

Hepatoblastoma is the most common liver cancer in childhood. These hepatic embryonal tumors exhibit the lowest mutational burden among pediatric tumors, raising the question if epigenetic changes could be relevant players in their tumorigenesis. We previously disclosed a pattern of low-level hypomethylation in non-repetitive sequences of hepatoblastomas in comparison to control liver tiss…
Germinative changes in genes predisposing to cancer may anticipate the age of onset of tumor involvement, and it has been estimated that between 25 and 30% of pediatric tumors can be associated with inherited or new genetic constitutive causes. Recently, Zhang et al (2016) reported germline mutations in cancer-predisposing genes in 8.5% of the children and adolescents with cancer; strikin…
