  1. ASYMMETRICALLY EXPRESSED GENES IN DEVELOPING CEREBRUM
    Daniel Geschwind; Fiscal Year: 2003
    ..abstract_text> ..
  2. THE GENETICS OF IDIOPATHIC BASAL GANGLIA CALCIFICATION
    Daniel Geschwind; Fiscal Year: 2004
    ..Physical mapping and candidate screening for mutations will be pursued as the region is narrowed to identify the IBGC gene. A genome scan will be performed in families who are not linked to the chr.14 locus. ..
  3. A Genomewide Search for Autism Susceptibilty Loci
    Daniel Geschwind; Fiscal Year: 2006
    ..All phenotypic and genotype data will be made accessible via the Internet on a rolling basis, further enhancing the value of this resource to the community. ..
  4. Identification of targets of FoxP2 in the brain
    Daniel Geschwind; Fiscal Year: 2006
    ..This proposal has a strong screening component in an area where no molecular mechanisms have been identified and fits well within the R21 framework. ..
  5. Phase I and Biological Studies of DB67 - A Blood Stable Camptothecin
    Markos Leggas; Fiscal Year: 2008
    ..Ultimately, the objective is to use DB-67 as a single agent or in combination with other molecular-targeted therapies or cytotoxics in frontline therapy with the goal to improve overall patient outcome. ..
