THE PROJECT AHC-MOME-IT HAS BEEN LAUNCHED, TO STUDY THE MOLECULAR MECHANISMS OF AHC

The aim of this Project is to create an "in vitro" model of the mutations causing AHC, in order to study the molecular pathogenesis of the disease and test some candidate compounds for the pharmacological treatment of AHC.
The Project is carried out by the Institute of Medical Genetics of the Catholic University in Rome, with the direction of Professor Fiorella Gurrieri and the participation of the I.B.AHC Consortium. The Italian Association A.I.S.EA and the Spanish Association AESHA are funding the first step of the Project.

INTERNATIONAL COLLABORATIVE STUDY GPC-AHC ON THE GENOTYPE-PHENOTYPE CORRELATION IN AHC, WITH THE INCLUSION OF ALL THE PATIENTS AVAILABLE IN I.B.AHC

The aim of the GPC-AHC Study is to determine if the different mutations (genotype) found in the AHC patients can statistically predict their different clinical pictures (phenotype), in terms of severity and types of symptoms.
The ultimate goal is to have a better idea of the defective malfunctioning caused by the AHC-mutations in the neurons in order to identify a possible group of candidate compounds as the most effective to correct such defect.
A large case-series (>100 patients) is essential for the success of this kind of studies, based on the statistical analysis of the data.
The GPC-AHC Study is carried out by International Consortium for the Research on ATP1A3 in AHC, composed by many National Clinical Reference Centers, by Genetic and Molecular Research Laboratories, by Patient Associations. For Italy, A.I.S.EA and the I.B.AHC Consortium are participating, thanks to which the clinical and genetic data of more than 40 patients available in I.B.AHC will be included in this Study.
The preliminary results of the correlation analysis will be presented at the 2nd Symposium on ATP1A3 in disease (Rome, 23 - 24 September 2013), www.symposium-atp1a3.tk); the definitive results will be published on a peer-review scientific journal. Professor Alexis Arzimanoglou, at the University Children's Hospital of Lyon, is the Coordinator of the Study; Rosaria Vavassori, of the Patient Association A.I.S.EA, is the project and data manager.

 

JULY 2012

THE PRIMARY GENE FOR ALTERNATING HEMIPLEGIA HAS BEEN FOUND!!!

The discovery has been possible thanks to a large collaborative study, involving clinical centers and genetic laboratories in Europe and America, with the financial and logistical support of the patient organizations in Italy, France and the United States.
The identified gene is ATP1A3 and encodes a protein functioning as sodium-potassium ion pump at the neuronal level. The gene discovery has been made possible through the application of the exome/genome sequencing, a very new technology that has recently revolutionized the research for genes responsible of many rare diseases.
All the details of the discovery have just been published by Nature Genetics, a prestigious international scientific journal.
Throw the initial sequencing of the exome of 7 patients the gene was identified by the researchers of the Duke University, and then, thanks to an impressive collaborative effort internationally sponsored and supported by the three main patient associations (in Italy, France and USA), the clinical centers and genetic laboratories from 13 different nations gathered to study further 95 patients, bringing to confirm the presence of causative mutations in the gene ATP1A3 in more than 75% of them. They are all de novo mutations, that’s to say present only in the patients and absent in all their parents.
For this collaborative study, A.I.S.EA provided the most extensive follow-up case series, contained in the Biobank and Clinical Registry I.B.AHC.

A NEW GENETIC STUDY BASED ON AN INNOVATIVE TECHNOLOGY WILL USE THE CINICAL DATA AND THE BIOLOGICAL MATERIAL KEPT IN I.B.AHC

The study "Exome Sequencing of Patients affected by Alternating Hemiplegia", presented by Prof. Fiorella Gurrieri and Prof. Giovanni Neri of the Clinics of Medical Genetics at the University Cattolica in Rome, has been definitively approved by the Scientific Committee and by the Board of Directors of A.I.S.EA.
The Study has been granted the access to the I.B.AHC Clinical Registry and Biobank and the financial support of the association (15.000 Euros).
Due to the high cost of the exome sequencing, that is a very new technique of genetic analysis, the DNA samples of only four AHC patients will be sequenced in this first preliminary phase of the Study.
The four patients will be selected by Pr Gurrieri in collaboration with Dr De Grandis and Giannotta, datamanagers of the I.B.AHC Registry, on the basis of their clinical and dysmorphic features.
