Background PCR amplification of target molecules involves sequence specific primers that flank the region to be amplified. While this technique is generally routine, its applicability may not be sufficient to generate a desired target molecule from two separate regions involving intron /exon boundaries. For these situations, the generation of full-length complementary DNAs from two partial genomic clones becomes necessary for the family of low abundance genes. Results The first approach we used for the isolation of full-length cDNA from two known genomic clones of Hox genes was based on fusion PCR. Here we describe a simple and efficient method of amplification for homeobox D13 (HOXD13) full length cDNA from two partial genomic clones. Specific 5' and 3' untranslated region (UTR) primer pairs and website program (primer3_www.cgv0.2) were key steps involved in this process. Conclusions We have devised a simple, rapid and easy method for generating cDNA clone from genomic sequences. The full length HOXD13 clone (1.1 kb) generated with this technique was confirmed by sequence analysis. This simple approach can be utilized to generate full-length cDNA clones from available partial genomic sequences.

This resource organizes NCBI information, resources, data, and tools and utilities on genomes including sequences, maps, chromosomes, assemblies, and annotations. Sequence and map data from the whole genomes of organisms. The genomes represent both completely sequenced organisms and those for which sequencing is in progress.

These v3.0 stratification BED files from the Global Alliance for Genomic Health (GA4GH) Benchmarking Team, the Genome in a Bottle Consortium and the Telomere-to-Telomere Consortium are intended as a standard resource of BED files for use in stratifying true positive, false positive, and false negative variant calls in challenging and targeted regions of the the genome. v3.0 stratifications contain new and revised stratification files and replace v2.0 stratifications.
