5S Ribosomal RNA

5S ribosomal RNA is an integral component of the large subunit of all cytoplasmic and most organellar ribosomes. Its small size and association with ribosomal as well as non-ribosomal proteins made it an ideal model RNA molecule for studies of RNA structure and RNA-protein interactions.
The purpose of this database is to provide information on nucleotide sequences of 5S rRNAs and their genes. The sequences for particular organisms can be retrieved as single files using a taxonomic browser or in multiple sequence structural alignments.

A CLAssification of genetic Mobile Elements

Prokaryotic Mobile Genetic Elements (MGE's) are central players in mobilizing genes, whether within a given genome (intra-cellular mobility) or between bacterial cells (inter-cellular mobility). Traditionally, MGE's have been classified as either bacteriophages, plasmids or transposons. This classification becomes more and more obsolete as many chimerical elements are identified, which display strong similarities with elements of different families.
We propose therefore ACLAME, a database dedicated to the collection and classification of MGEs from various sources, comprising all known phage genomes, plasmids and transposons.

ALPORT Syndrome and COL4A5

Alport Syndrome is a progressive renal disease with cochlear and ocular involvement. The most common form (~80%) is inherited in an X-linked pattern. X-linked Alport Syndrome (OMIM #301050) is caused by mutations in the type IV collagen alpha chain 5 (COL4A5). The aim of this database is to record all known variants in the COL4A5 gene and their clinical significance. The GenBank sequence NC_000023.9 is used as the reference sequence. The Human Genome Variation Society nomenclature has been used to describe COL4A5 mutations, as well as original nomenclature described by Zhou et al (1994), which includes 202 nucleotides of 5' UTR. ARUP offers full gene sequencing analysis (test 0051786) for classic X-linked Alport syndrome (80% of mutations) and targeted testing for p.C1564S (c.4692G>A), p.L1649R (c.4946T>G), p.R1677Q (c.5232G>A) mutations for adult type Alport syndrome (test 0051710).

Androgen Receptor Database

Constitutional mutations in the androgen receptor gene (AR) impair androgen - dependent male sexual differentiation to various degrees. Somatic mutations in the AR have been found in metastatic prostate cancer. Severe constitutional androgen insensitivity (AI) yields an external female phenotype. Partial constitutional AI yields a range of external genital phenotypes that vary from near - normal female to normal or near - normal male, with or without gynecomastia and other relatively "mild" signs of undervirilization. Some have suggested that clinical severity of AI be divided into three degrees: complete, partial, (when there is appreciable external genital ambiguity) and mild (for the least severe forms). Others have graded severity into seven degrees . The current version of the AR mutation database retains the complete / partial bifurcation of the original database, but provides additional information on the external genitalia and on sex - of - rearing. When external genital ambiguity is appreciable, the sex - of -rearing implies that the external genitalia were predominately male or female. Because different clinical degrees of AI are sometimes seen within families or between those with the same mutation, the new version of the database has an entry for family history.

The Histone Sequence Database is a curated collection of sequences and structures of histones and non-histone proteins containing histone folds, assembled from major public databases. Here, we report a substantial increase in the number of sequences and taxonomic coverage for histone and histone fold-containing proteins available in the database. Additionally, the database now contains an expanded dataset that includes archaeal histone sequences. The database also provides comprehensive multiple sequence alignments for each of the four core histones (H2A, H2B, H3, and H4), the linker histones (H1/H5), and the archaeal histones. The database also includes current information on solved histone fold-containing structures.

Moreover, Y chromosomal profiling can trace back paternal lineages into the past and has thus been proven a useful tool in genealogical and kinship testing. The individuality of the male-specific part of the Y chromosome can be optimally explored by the Y-STR haplotype analysis using a set of highly variable short tandem repeat markers approved by the forensic and scientific community.
