Abstract: | The delta-aminolevulinate dehydrase (E.C. 4.2.1.24) gene frequencies were investigated by starch gel electrophoresis in 711 unrelated individuals from the Düsseldorf area. The following gene frequencies were found: ALADH1 0.929, ALADH2 0.071. The frequency reported for ALADH1 is only slightly higher than that for Italy. |
