Clinical and genetic findings in Hungarian pediatric patients carrying chromoso...

The short arm of chromosome 16 (16p) is enriched for segmental duplications, making it susceptible to recurrent, reciprocal rearrangements implicated in the etiology of several phenotypes, including intellectual disability, speech disorders, developmental coordination disorder, autism spectrum disorders, attention deficit hyperactivity disorders, obesity and congenital skeletal disorders. In our clinical study ...

Comprehensive clinically oriented workflow for nucleotide level resolution and ...

We present a comprehensive clinically oriented workflow for large-insert genome sequencing (liGS)-based nucleotide level resolution and interpretation of de novo (dn) apparently balanced chromosomal abnormalities (BCA) in prenatal diagnosis (PND). Retrospective or concomitant with conventional PND and liGS, molecular and newly developed clinically inspired bioinformatic tools (TAD-GConTool and CNV-ConTool) are ...

As doenças raras na Europa: o enquadramento português

A EUCERD Joint Action (EJA) para as Doenças Raras (DR) integrou cinco domínios: planos nacionais e estratégias, nomenclatura internacional para DR, serviços sociais especializados, qualidade dos cuidados/centros de referência e integração de iniciativas em DR. O objetivo deste artigo é descrever o enquadramento português nas DR. Em novembro de 2014 foi realizado um workshop em Portugal com oito países participa...

Genomic landscape of balanced cytogenetic abnormalities in subjects with multip...

Balanced chromosomal abnormalities (BCAs) represent a unique class of genomic variation that involves large rearrangement of the chromosomes. To date their detection has been limited to cytogenetic resolution as most first-tier genetic screening methods are blind to their presence. We defined the genomic landscape of de novo BCAs associated with human congenial anomalies in 235 subjects using whole-genome seque...

Citogenética de Próxima Geração: Implementação e primeiros resultados em Portugal

Introdução: As alterações cromossómicas estruturais provocam doenças de severidade variável que acarretam sofrimento individual e familiar signifi cativo. Para compreensão da sua etiologia e estabelecimento de um possível prognóstico, uma adequada correlação fenótipo-genótipo é fundamental. O presente estudo faz parte do projeto intitulado àCitogenética de Próxima Geração Irrompe nos Cuidados de Saúde e Contrib...

The genomic landscape of balanced cytogenetic abnormalities associated with hum...

Despite the clinical significance of balanced chromosomal abnormalities (BCAs), their characterization has largely been restricted to cytogenetic resolution. We explored the landscape of BCAs at nucleotide resolution in 273 subjects with a spectrum of congenital anomalies. Whole-genome sequencing revised 93% of karyotypes and demonstrated complexity that was cryptic to karyotyping in 21% of BCAs, highlighting t...

Early results of next-gen cytogenetics implementation in Portugal

Background: Most approaches are insensitive to the full mutational spectrum of chromosome rearrangements associated with human developmental abnormalities. Therefore, our aim is to introduce next-generation sequencing (NGS) into clinical cytogenetics, creating a sequence-based NextGen Cytogenetics to catalyze a dramatic advancement in clinical diagnostics. Methods: Twenty families with chromosome rearrangement-...
