Description

Our main interest has always been to identify  the molecular causes of rare chromosome  rearrangements in patients with neurodevelopmental disorders, with emphasis on the Phelan-McDermid Syndrome (also known as 22q13.3 deletion Syndrome), and conducting genotype/phenotype correlations.

The most recent activity relates to the detection of genomic variations  for neurodevelopmental disorders  by the use of state-of-the-art high resolution molecular techniques (genomic array and next generation sequencing) and implementing these techniques in routine diagnostics. This approach provides an opportunity to obtain new insights on molecular mechanisms underlying chromosomal instability and to highlight any possible genomic signature favoring their occurrence.
