Abstract: The present invention related to the proline rich transmembrane protein 2 (PRRT2) gene, and the identification of mutations and variations in PRRT2 that give rise to seizure and movement disorders. Accordingly, the present invention provides methods for the diagnosis or prognosis of such disorders by identifying alterations in the PRRT2 gene. Identification of alterations in the PRRT2 gene also enables the identification of subjects with an increased likelihood of having an offspring predisposed to such disorders. The present invention also provides an isolated nucleic acid molecule comprising an alteration in the PRRT2 gene, wherein said alteration produces a seizure and/or movement disorder phenotype. Also provided is an isolated PRRT2 polypeptide that comprises an alteration which produces a seizure and/or movement disorder phenotype.

Abstract: Methods and kits for the diagnosis of illnesses related to protocadherin 19 (PCDH19) protein deficiency or altered PCDH19 protein function are provided, as well as methods and kits for the identification of a predisposition to such illnesses and methods of screening subjects to identify carriers of such illnesses and methods and kits for the therapeutic or prophylactic treatment of PCDH19 deficiency or altered PCDH19 protein function. Further, nucleotide and amino acid sequences corresponding to a complete PCDH19 open reading frame (ORF), mutant sequences encoding non-functional PCDH19 mRNA or altered PCDH19 mRNA are described along with transformed cells and non-human transgenic animals comprising wild-type or mutant PCDH19 ORF nucleotide sequences.
