Abstract

Single-copy sequences can be enzymatically amplified from genomic DNA by the polymerase chain reaction. By using unequal molar amounts of the two amplification primers, it is possible in a single step to amplify a single-copy gene and produce an excess of single-stranded DNA of a chosen strand for direct sequencing or for use as a hybridization probe. Further, individual alleles in a heterozygote can be sequenced directly by using allele-specific oligonucleotides either in the amplification reaction or as sequencing primers. By using these methods, we have studied the allelic diversity at the HLA-DQA locus and its association with the serologically defined HLA-DR and -DQ types. This analysis has revealed a total of eight alleles and three additional haplotypes. This procedure has wide applications in screening for mutations in human genes and facilitates the linking of enzymatic amplification of genes to automated sequencing.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
