Abstract

The gene frequency of the transthyretin (TTR) mutation (Val122Ile) was studied in African and African-American populations. The African populations analyzed included the Zulu and Xhosa of South Africa, and Yorubas from the city of Ibadan, Nigeria. The African-American population included patients at the Veterans Affairs (VA) Medical Center, Indianapolis, and newborns from a local hospital in Indianapolis. The Val122Ile TTR mutation was identified in 1 of 55 Zulu, 0 of 34 Xhosa, 0 of 9 Nigerian subjects, 5 of 51 Veteran patients, and 3 of 103 newborns. Assuming the 2.91% prevalence in newborns to be the norm, there is a significant increased prevalence in the VA patient population.
