A great deal of the last quarter of a century’s astonishing progress in understanding and treating human disease is attributable to the existence of public databases where information about DNA sequences, protein sequences, protein structures, human variation, etc. is stored and is freely available to all interested investigators. Information that is developed by one laboratory to help answer a...

Microsatellites (SSR--simple sequence repeats, STR--short tandem repeats, SSLP--simple sequence length polymorphism, VNTR--variable number of tandem repeats) are the class of repetitive DNA sequences present in all living organisms. Particular characteristics of microsatellites, such as their presence in the genomes of all living organisms, high level of allelic variation, co-dominant mode of i...

Background Late-Onset Alzheimer’s Disease (LOAD) is characterized by genetic heterogeneity and there no single model explaining the mode of inheritance. Short tandem repeats (STRs), which are hyper-mutable sequences in human genome could explain some missing heritability LOAD. STRs involved several neuro-degenerative disorders. We systematically evaluated impact 31 disease-associated on neuropa...

Tandem repeats in DNA have been under intensive study for many years, first, as a consequence of their usefulness as genomic markers and DNA fingerprints and more recently as their role in human disease and regulatory processes has become apparent. The Tandem Repeats Database (TRDB) is a public repository of information on tandem repeats in genomic DNA. It contains a variety of tools for repeat...

Citrus greening (huanglongbing) is the most destructive citrus disease worldwide. The disease is associated with three species of 'Candidatus Liberibacter' among which 'Ca. Liberibacter asiaticus' has the widest distribution. 'Ca. L. asiaticus' is commonly transmitted by a phloem-feeding insect vector, the Asian citrus psyllid Diaphorina citri. A previous study showed that isolates of 'Ca. L. a...

The performance of a multiplex assay with 52 autosomal single nucleotide polymorphisms (SNPs) developed for human identification was tested on 124 mother-child-father trios. The typical paternity indices (PIs) were 10(5)-10(6) for the trios and 10(3)-10(4) for the child-father duos. Using the SNP profiles from the randomly selected trios and 700 previously typed individuals, a total of 83,096 c...
