AB We studied the genetic pattern of inheritance of the ratio between
circulating CD4+ and CD8+ T lymphocytes in a population of healthy
donors. The distribution of the CD4/CD8 ratio in males and females was
significantly different and was significantly affected by age. In 46
randomly selected families, the parental CD4/CD8 ratio significantly
influenced the ratio in offspring. Complex segregation analysis of the
data rejected the non-genetic hypothesis; among the genetic models
tested, a major recessive gene with a polygenic component and random
environmental effects was the most parsimonious model. These findings
indicate that the ratio of CD4+ and CD8+ T cells is genetically
controlled in humans.
