Abstract
We describe a 6-year-old boy carrying a de novo 5Mb interstitial deletion of chromosome 8p23.1 identified by means of oligonucleotide array comparative genomic hybridisation (array CGH), who showed the typical signs of 8p23.1 deletion syndrome, including congenital heart defects, microcephaly, psychomotor delay and behavioural problems. In order to estimate the role of suggested candidate genes, we compared the deletion of our patient with other previously reported and molecularly characterised deletions that have been re-evaluated on the basis of the current genetic map data. The inclusion of TNKS gene in the deletion interval without any phenotypical signs of Cornelia de Lange syndrome (CdLS) invalidates TNKS as a plausible candidate gene for the syndrome itselfPubblicazioni consigliate
