The pseudoautosomal region of the human X and Y chromosomes is subject to frequent X-Y recombination during male meiosis. We report the finding of two pseudoautosomal loci, DXYS20 and DXYS28, characterized by highly informative restriction fragment length polymorphisms (RFLPs). The pseudoautosomal character of DXYS20 and DXYS28 was formally demonstrated by comparing their transmission to 45,X a...
Hypophosphatasia is a rare disease characterized by low serum levels of tissue non-specific alkaline phosphatase (TNSALP) and a spectrum of skeletal disease varying from the severest form with death in utero to mild with no clinical abnormality in adults. Currently, the diagnosis of hypophosphatasia is made on the basis of clinical findings, radiography, low serum alkaline phosphatase levels an...
Several of the heterogeneous clinical manifestations of systemic lupus erythematosus have been associated with specific autoantibodies. Associations between HLA class II antigens and autoantibodies to the ribonucleoproteins Ro(SSA) and La(SSB) have been reported in these patients. Because HLA class II molecules present antigen to T cell receptors (TCRs), we have searched for a TCR gene associat...
Restriction fragment length polymorphisms (RFLPs) identified in the ribosomal-DNA (rDNA) repeat were used for molecular strain differentiation of the dermatophyte fungus Trichophyton rubrum. The polymorphisms were detected by hybridization of EcoRI-digested T. rubrum genomic DNAs with a probe amplified from the small-subunit (18S) rDNA and adjacent internal transcribed spacer (ITS) regions. The...
We have sampled the mycorrhizal roots of 76 snow plants (Sarcodes sanguinea, Monotropoideae, Ericaceae) in two areas of the Sierra Nevada of California that are ∼180 km apart. To identify the fungal symbionts associated with these plants, we first analyzed restriction fragment length polymorphisms (RFLPs) of the internal transcribed spacer region (ITS) of the fungal nuclear ribosomal repeat. Fu...
In this study, restriction fragment length polymorphisms (RFLPs) were identified with an immunoglobulin variable heavy chain region (Ig VH) probe and the inheritance of the polymorphisms was analyzed in families. Linkage within the VHII gene cluster and between the VHII and Ig CH genes was investigated by lod (logarithm of odds) score analysis. In addition, the position of the VHII genes was de...
In the west of Scotland use of a single intragenic restriction fragment length polymorphism (F9(VIII)/TaqI) allowed definitive genetic counselling for 45% of females at risk of being carriers for haemophilia B. Two further intragenic RFLPs, F9(VIII)/XmnI) and F9(VIII)/DdeI, have been applied to this population and by using all three polymorphisms the carrier status could be determined in 68% of...
