    Notes: Various common C4 gene products were isolated from serum by immunoprecipitation. After reduction the C4 α-, β-, and γ-polypeptide chains were studied by two-dimensional electrophoresis. Isoelectrofocusing was performed in the first dimension and sodium dodecyl sulphate polyacrylamide gradient gel electrophoresis in the second. The charge differences behind the electrophoretic C4 polymorphism were shown to reside in the 95,000-u(atmic mass units) α-chain. Charge variation closely mirroring the α-chain differences were also found in a 49,000-u fragment of the α-chain, most probably C4d. The basic β-chain could not be studied in detail, but no differences were observed with regard to molecular weight or charge of the γ-chains of the different C4 gene products.

    Notes: Electrophoretic and serologic investigations of C4 in serum samples from a family material, showed that a weak, or partial, inhibition of anti-Rg sera, was an inherited property of some of the C4 haplotype products. The weak Rg activity was strongly, but not absolutely associated with the C4 FI and C4 I haplotypes.

    Notes: C4-coated Ch(a+) red blood cells (RBC) were used as indicator cells in a serum inhibition reaction of anti-Cha, for the determination of the Ch group of serum. This serological study, combined with electrophoretic studies of C4 in a family material, showed that the C4M haplotype product was associated with partial inhibition of anti-Cha.

    Notes: [Auszug] Fig. 1 A 'family tree' of the populations studied. Dimensions are time in generations (in brackets) and assumed numbers of ancestral B8 loci (minimum plausible estimates). Iceland was settled in AD 874 by Norsemen with Irish slaves and had a population of over 70,000 by AD 1100; the Nordic and ...

    Notes: [Auszug] Clinically the disease is characterised by proteinuria, cor-neal opacities and normochromic anaemia with decreased erythrocyte life span. The plasma cholesteryl ester and lyso-lecithin concentrations are decreased, and free cholesterol and lecithin usually increased. Studies of the LCAT-deficient ...

    Description / Table of Contents: Zusammenfassung Es wird die Analyse des Polymorphismus der Länge eines Restriktionsfragments (RFLP, restriction fragment length polymorphism) beschrieben, wobei eine zweifache Spaltung von DNA-Präparaten mit XbaI und BglII Restriktionsenzymen und Hybridisierung mit C4 und HLA-DR angewandt wird. Bei der gewählten Untersuchungstechnik lassen sich zahlreiche individuelle Variationen in den C4 und DR Genregionen nachweisen. In einem Untersuchungsgut von 46 nicht verwandten Personen wurden in beiden Systemen 37 verschiedene Phänotypen-Muster gefunden, wobei die vorläufigen Werte des Diskriminations-Indexes mit 0.865 für C4 und mit 0.914 für DRβ berechnet wurden. Die Wahrscheinlichkeit einer Übereinstimmung bei Anwendung beider Systeme dürfte etwa bei 1.5 × 10−2 liegen. Die Brauchbarkeit dieser Methode zur Identifizierung individueller Blutspuren wurde anhand der DNA demonstriert, die aus 6 Monate alten, getrockneten Blutspuren von sieben Personen des Untersuchungskollektivs gewonnen wurde. Alle Proben konnten durch Vergleich der DNA-Muster mit denen der zuvor erstellten den entsprechenden Personen eindeutig zugeordnet werden. Es zeigten sich im DNA-Muster der Blutspuren keine u. U. lagerungsbedingte Veränderungen. Aus dieser unter Laborbedingungen durchgeführten D4 und DRβ DNA-Untersuchung kann geschlossen werden, daβ die DNA-Hybridisierungstechnik zukünftig als wichtiges Hilfsmittel bei der Spurenanalyse eingesetzt werden kann.
    Notes: Summary A restriction fragment length polymorphism analysis using double digestion of DNA preparations with XbaI and BglII restriction enzymes and hybridization with C4 and HLA-DR probes is described. The typing conditions selected reveal extensive individual variation in both C4 and DR gene regions. In our panel of 46 unrelated individuals, 37 different phenotypic patterns were recognized when both probes were used, and preliminary discriminative power values of 0.865 and 0.914 were calculated for C4 and DRβ, respectively. The probability of a chance match using both systems is probably about 1.5 · 10−2. The potential of this method for individual identification of blood stains was demonstrated on DNA prepared from 6-month-old dried blood stains from seven panel individuals. The seven individuals were all identified when comparing stain DNA patterns with panel control patterns. No RFLP pattern changes were observed following storage of blood stains. Based on these experiments with C4 and DRβ DNA typing under laboratory conditions, it is concluded that DNA typing with such probes may become a powerful tool in future stain identification analyses.

    Notes: Summary C6 typing was performed in a family material by two different techniques: serum or plasma samples were subjected either to high-voltage agarose gel electrophoresis or to isoelectric focusing in polyacrylamide gel slabs. Proteins with C6 activity were then visualized by a specific, hemolytic assay. In 81 unrelated adults within the family material the following allele frequencies were found: C6 A:0.61 and C6 B:0.39. Linkage studies exclude linkage between C6 and HLA region marker loci, and also between C6 and another chromosome 6 marker locus PGM3.

    Notes: Summary Linkage relations between the C6 and 33 other genetic marker loci have been analyzed in Norwegian pedigrees, including 114 matings with 388 informative children, by use of the MOSM computer program. No suggestion of linkage was found. Very close or close linkage (θ〈0.06) has been ruled out for males between C6 and the following 19 marker loci: GPT, HLA+Bf, Rh, C3, Hp, PGM 3, Km, Gm, Fy, Gc, AB0, Jk, GLO 1, K, MNSs, PTC, ACP 1, PGM 1 and Pi. For several of the relations even loose linkage is unlikely.
