title: Cross-cultural comparison of Lp(a) profiles.
abstract: Lipoprotein(a) (Lp(a)) and apolipoprotein(a) (apo(a)) phenotypes as genetic markers for coronary heart disease (CHD) have been the focus of great interest in recent times. Included in this study were four Australian populations comprising 348 Anglo-Celtic Melburnians (157 men and 191 women), 339 Chinese Melburnians (169 men and 170 women), 402 South Asian Melburnians (216 men and 186 women) and 394 Aboriginal Australians from Western Australia (175 men and 219 women). Plasma Lp(a) concentrations were more highly skewed towards the lower range in the Chinese and Aboriginal groups than in the Anglo-Celtics and South Asians. Approximately 33% of Anglo-Celtics, 20% Aboriginals, 13% Chinese and 44% South Asians had plasma Lp(a) levels above the generally accepted risk threshold values of 300 mg/L. In Aboriginals and Chinese, the S4 apo(a) phenotype predominated while in Anglo-Celtics and South Asians, the highest frequency occurred in the S3 phenotype. In the S4 phenotype, Lp(a) values varied between the four populations but there was no significant difference in concentration between gender.
