Research Bio
Dr. Katzman's research interests include placental pathology and development disorders, such as DiGeorge syndrome. He has begun investigating the ability to confirm morphologically diagnosed hydatidiform moles using fluorescent in situ hybridization (FISH) in cases where cytogenetic analysis on submitted tissue is unhelpful (no growth) or cannot be processed due to fixation. FISH could become an alternative diagnostic method for these specimens in our clinical laboratory. Dr. Katzman has also investigated the enigmatic "maternal floor infarction" in the placenta and is particularly interested in its identification as a possible etiology in recurrent first trimester losses.
Dr. Katzman developed an interest in DiGeorge syndrome and the deletion 22q11.2 spectrum while in pediatric pathology fellowship. He has studied a cohort of autopsied patients with congenital heart disease compiled in the Cardiac Registry of Boston Children's Hospital to identify a subpopulation with the 22q11.2 deletion. He used the polymerase chain reaction (PCR) to evaluate loss of heterozygosity (LOH) in this chromosome region for each patient. He hopes to confirm his data by performing FISH on the same cases and to develop a PCR assay for the 22q11.2 deletion as an alternative to the currently used clinical FISH assay.
