Academic Interests: Clinical Cytogenetics

Research in our laboratory focuses on the conventional and molecular characterization of human developmental disorders. Specifically, we are interested in the mechanisms and consequences of chromosomal abnormalities, which result in abnormal phenotype, mental retardation and behavioral disorders. Research work is aided by the use of Fluorescence In Situ Hybridization for the identification and characterization of microdeletions and cryptic telomere rearrangements. Clinical services include tissue culture and cytogenetic diagnosis for amniotic fluid, blood, bone marrow, solid tissue and tumor specimens and FISH analysis of genetic disorders and syndromes.
