A total of 1, 041 syphilis patients of both sexes and different ethnic origin (Chinese, Malay, and Indian) were investigated for the distribution of ABO blood groups and haemoglobin genotypes. There was no significant difference in the incidence of ABO blood groups and abnormal haemoglobins between disease and control series in any of the racial groups.
From the above series, 819 male patients were investigated for the incidence of G6PD deficiency. There was no significant difference in the incidence of this genetic marker in disease and normal series.
