    Notes: Summary Isoelectric focusing (IEF) with carrier ampholytes was used for the determination of transferrin C subtypes and transferrin B and D variants in a sample of 1125 unrelated individuals from Southern Germany. The observed TfC allele frequencies were Tf*C1=0.7872, Tf*C2=0.1365, and Tf*C3=0.0675. The rare C subtype C6 was observed twice. A new C subtype, called C10, was observed and identified by IEF with immobilized pH gradients. The rare C subtypes C4 and C8 were also studied by this method. TfB and TfD variants were found with a heterozygous frequency of 1.53%. One new TfD was found which is located between D1 and D2 and therefore named D1-2. Evidence for a Tf null allele was obtained in a child and the putative father; they were considered to be heterozygous for an allele Tf0. The theoretical exclusion rate for paternity examinations was calculated for the Tf system and found to be 17.95%.

    Notes: Summary The genetic types of the properdin factor B were analyzed by isoelectric focusing on polyacrylamide gels and subsequent immunofixation. Sera from 516 unrelated, healthy individuals from Southern Germany were examined. Two new subtypes of the Bf*S allele were observed. They were provisionally named Bf*Sb1 and Bf*Sb2 (b = basic), since the position of their bands is located slightly towards the cathode. Whereas Bf Sb2 has, thus far, been found only in a single individual, Bf Sb1 was found in five unrelated persons and in a mother and her child indicating a simple codominant mode of inheritance. The combined frequency of the Bf*Sb alleles was calculated to be 0.0067.

    Notes: Summary The human serum transferrin (Tf) system was analyzed by isoelectric focusing (IEF) with immobilized pH gradients. For the demonstration of the genetic variability the Fe1-Tf region was chosen. The pH range suitable for analysis of the Tf system was pH 5.20 to pH 5.75. The phenotypes of the common six TfC subtypes are described. No further heterogeneity among TfC1, TfC2, and TfC3 was noted. Also presented are the phenotypes of the TfC6 subtype, and of three different TfB and three different TfD variants. IEF with immobilized pH gradients appears to be a suitable method for the analysis of the inherited transferrin polymorphism.

    Description / Table of Contents: Zusammenfassung Die genetischen Variationen des Protease-Inhibitors (Pi) a 1-Antitrypsin wurden mit Hilfe der Isoelektrofokussierung in einer Stichprobe von 347 nicht verwandten Personen aus Süddeutschland untersucht. Es wurden sechs häufige PiM-Untergruppen und die relativ häufigen Varianten PiS und PiZ differenziert; zudem fanden sich die seltenen Varianten PiT, Pi〈L, PiL, PiI, PiF sowie eine als PiZl bezeichnete Variante. In dieser Stichprobe wurden folgende Allelfrequenzen berechnet: PiM1=0.6917, PiM2=0,1686, PiM3=0,0865, PiS=0,0230, PiZ=0,0187 und Pi*=0,0115. In 82 Familien fand sich keine Abweichung vom angenommenen autosomal kodominanten Vererbungsmodus. Die Verwendbarkeit des Pi-Systems für die Paternitätsbegutachtung wird diskutiert.
    Notes: Summary Genetic variation of the protease inhibitor (Pi) a 1-antitrypsin was analyzed by isoelectric focusing on polyacrylamide gels in a sample of 347 unrelated individuals from Southern Germany. Six common subtypes of PiM were observed as well as the relatively frequent variants PiS and PiZ and the rare variants PiT, Pi〈L, PiL, PiI and PiF. Also, a variant called PiZl was found. The frequency of alleles in this sample was PiM1=0.6917, PiM2=0.1686, PiM3=0.0865, PiS=0.0230, PiZ=0.0187, and Pi*=0.0115. In 82 families the distribution of Pi types was in agreement with an autosomal codominant mode of inheritance. The application of Pi classification in cases of disputed paternity is discussed.

    Description / Table of Contents: Zusammenfassung Mit Hilfe der isoelektrischen Fokussierung in Polyacrylamidgelen (PAGIF) wurden 450 Proben von nicht verwandten Personen aus Süddeutschland untersucht. Es wurden drei häufige Untergruppen Tf C1, C2-1 und C2 differenziert, sowie die seltenen Varianten TfB1, B1-2, B2, D1, D1-2, D2 und D3 beobachtet. Die Allelfrequenzen in dieser Stichprobe betrugen: TfC1=0,8544, TfC2=0,1367, TfB1=0,0011, TfB1-2=0,0022, TfB2=0,0045, and TfD1=0,0011. Die Untersuchung von 73 Elternpaaren mit ihren Kindern ergab keine Abweichung vom angenommenen autosomal kodominanten Erbgang. Modifizierung der Methode durch Zusatz von 0,01 M FeCl3 zu den Seren vor der Auftrennung ließ weitere Variation erkennbar werden und erlaubte sechs häufige Untergruppen zu differenzieren, nämlich C1, C2-1, C2, C3, C3-1 und C3-2.
    Notes: Summary A sample of 450 sera from unrelated individuals from Southern Germany was examined by isoelectric focusing on polyacrylamide gels. Three common subtypes, TfC1, C2-1, and C2, were differentiated. In addition, the rare variants TfB1, B1-2, B2, D1, D1-2, D2, and D3 were observed. The frequencies of the Tf alleles in our sample were found to be: TfC1=0.8544, TfC2=0.1367, TfB1=0.0011, TfB1-2=0.0022, TfB2=0.0045, and TfD1=0.0011. Analysis of 73 parents with 73 children did not show deviations from the expected mode of inheritance. Modification of the method by addition of 0.01 M FeCl3 to the sera prior to examination did, however, reveal further variation and permitted the distinction of six subtypes, C1, C2-1, C2, C3, C3-1, and C3-2.

    Description / Table of Contents: Zusammenfassung Der PGM1-Polymorphismus wurde mit Hilfe der Isoelektrofokussierung auf Agarose-Gel-Platten untersucht. Mit dieser modifizierten Methode lassen sich die PGMI-Untergruppen an Hämolysaten ohne Schwierigkeiten klassifizieren. Neun der erwarteten zehn Phänotypen wurden in einer Stichprobe von. 470 nichtverwandten Personen aus Süddeutschland beobachtet. Folgende Allelhäufigkeiten wurden ermittelt: PGM 1 1+ = 0,6212, PGM 1 1- = 0,1224, PGM 1 2+ = 0,2043, PGM 1 2- = 0,0521.
    Notes: Summary PGM1 subtypes were determined in red cell hemolysates by isoelectric focusing on agarose gel plates. By this modified procedure PGM1 subtypes may be readily classified. Nine of the 10 expected phenotypes were found in a sample of 470 unrelated individuals from Southern Germany. The frequencies for the four alleles were found to be: PGM 1 1+ = 0.6212, PGM 1 1- = 0.1224, PGM 1 2+ = 0.2043, PGM 1 2- = 0.0521.

    Description / Table of Contents: Zusammenfassung Die Untergruppen des Protease-Inhibitors (Pi) α1-Antitrypsin wurden im Serum von 752 nichtverwandten Personen aus Süddeutschland bestimmt. Mit Hilfe der isoelektrischen Fokussierung ließen sich dabei neun häufige PiM-Untergruppen neben mehreren seltenen Pi-Varianten unterscheiden. Die Existenz eines vierten PiM-Subtypenallels wurde durch Familienuntersuchungen bewiesen. In unserer Stichprobe errechnete sich für PiM4 eine Allelfrequenz von 0.018. Die übrigen Allelfrequenzen wurden mit den Untersuchungsergebnissen anderer Autoren verglichen. Die Anwendung der Pi-Untergruppenbestimmung in der Vaterschaftsuntersuchung wird besprochen.
    Notes: Summary Subtypes of the protease inhibitor (Pi) α1-antitrypsin were determined in sera from 752 unrelated individuals from Southern Germany. By isoelectric focusing nine common PiM subtypes were distinguished and several rare Pi variants were observed. Family studies confirm the existence of a fourth PiM suballele. The frequency of PiM4 was found to be 0.018. A survey of the distribution of Pi alleles is given; the application of Pi subtyping in cases of disputed paternity is discussed.
