This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. Kaposi's sarcoma-associated herpesvirus (KSHV) is detected consistently in Kaposi?s sarcoma (KS). Because of its dramatic sequence variation, the K1 gene has been used to classify KSHV. We found a diverse array of KSHV subtypes A1, A2, A3, A5, B1, B2, and C3 in 23 Cuban KS samples containing several novel sporadic insertions/deletions in subtypes A and C. The molecular epidemiology of the KSHV subtypes seems to reflect the unique mixed ethnic background of the Cuban population.
