To determine the frequency of familial hypoalphalipoproteinemia in the general population due to mutation of the apolipoprotein A-I (apo A-I) gene, we analyzed sequence variations in the apo A-I gene. The subjects were 67 children with a low high-density lipoprotein (HDL) cholesterol level (less than or equal to 38 mg/dl, below the fifth percentile in the population of this study) who were screened from 1254 schoolchildren through a school survey, Four different mutations with deleterious potential, three frameshifts and one splice site mutation, were identified in four of the subjects. The plasma apo A-I levels of the four children with apo A-I gene mutations were reduced to approximately half of the normal levels and were below the first percentile of the general population distribution (80 mg/dl), Thus, the frequency of hypoalphalipoproteinemia due to a mutant apolipoprotein A-I gene was estimated at 6% (95% CI: 2.4-14.4%) in the subjects with low HDL cholesterol levels and 0.3% (95% CI: 0.1-0.8%) in the Japanese population. This suggests that familial hypoalphalipoproteinemia due to apo A-I gene mutations is relatively common.
