Two Pvu II RFLPs recognized by a human immunoglobulin alpha heavy chain probe (IgHAI)

Two RFLPs in human inter-alpha-trypsin inhibitor heavy chain gene ITIH2 on chromosome 10.

SOURCE AND DESCRIPTION OF CLONE : The 0.8 kb Eco RI / Bam HI fragment of lambda HuHITI-9 (1) used as a probe codes for human heavy chain H2 of the inter-alpha-trypsin inhibitor (2). POLYMORPHISMS : Kpn 1 (GGTAC/C) identifies one invariant band at 8.5 kb and a diaJlelic polymorphism with DNA fragments at 26.0 kb or 20.0 kb. Msp I (C/CGG) identifies three invariant bands at 2.35 kb, 2.1 kb and 1....

Human immunoglobulin constant heavy G chain ( IGHG

The distinguished alternative GM allotypes localized in immunoglobulin constant heavy G chains, IGHG (Fc) (GM) genes on chromosome 14q32.3 define two unique variants of respectively IgG3, IgG1 and IgG2 subclass, with different structures and functions. The IGHG allele (allotypes), expressed in homozygous or heterozygous forms, are assessed by new serological methods. Fixed combinations of 3, ...

Immunoglobulin heavy-chain-associated amyloidosis.

Immunoglobulin- or multiple myeloma-associated amyloidosis has been distinguished by the tissue deposition of Congophilic, fibrillar protein consisting of light chains or light-chain fragments (AL amyloidosis). We now report the isolation and characterization of another form of immunoglobulin-associated amyloid obtained from a patient who had extensive systemic amyloidosis and in whom the amylo...

Multiple gene deletions within the human immunoglobulin heavy-chain cluster.

Two subjects, of 11,000 healthy individuals screened, were found to be missing three and four immunoglobulin isotypes, respectively (IgA1, IgG2, and IgG4; IgA1, IgG2, IgG4, and IgE), and have been analyzed at the DNA level by means of Southern blotting and Ig heavy-chain-specific probes. A broad deletion within the heavy-chain constant region (C) gene cluster was found on chromosome 14 of both ...
