Research Summary:

Dr. Berger-Zaslav is involved in clinically based research using cytogenetic and molecular cytogenetic techniques to elucidate cryptic unidentifiable structural chromosome abnormalities, euchromatic and heterochromatic variant chromosomes and the significance of these abnormalities with respect to phenotype.  This research is performed on prenatal, pediatric and adult patients with inherited and acquired (cancer) chromosome abnormalities.

Clinical Practice:

Dr. Berger-Zaslav is Board certified in Clinical Cytogenentics (1996) and she also holds a New York State Certificate of Qualification for the area of Cytogenetics.  Dr. Berger-Zaslav is the Head of Cytogenetics at Stony Brook University Medical Center.  Under her direction, the Cytogenetics Laboratory performs chromosome analysis on patients undergoing prenatal diagnosis, patients with inherited genetic disorders, mental retardation, developmental delay, autism, and adults and children with cancer.  This involves standard chromosome analysis, molecular cytogenetics (FISH) and subtelomere analysis (FISH) on: bone marrow, solid tumors, lymph nodes, peripheral bloods, amniotic fluid, and products of conception.  The Cytogenetic laboratory is the ONLY laboratory in Suffolk County certified to perform cytogenetic analyses on pediatric patients with acute lymphoblastic leukemia (ALL) for the Children's Oncology Group (COG).  Dr. Berger-Zaslav reviews and reports on all cases evaluated in the Cytogenetics laboratory.  She personally notifies the referring physician with abnormal results and is available for consultation and questions.  Dr. Berger-Zaslav developed and instituted the first Cytogenetics course for the Medical Technology School at Stony Brook University, and is actively involved in teaching medical students, residents, and attendings.
