Hello Paresh,

This place is as good as any to ask.  Depending on what you are looking for,
I would recommend a possible search starting with OMIM (Online Mendelian
Inheritance in Man).  The URL for your search would be:


Proving you have access to WWW.  OMIM in general would be:


then choose "OMIM -- Online Mendelian Inheritance in Man"

In anycase you can start from the GDB Homepage, use OMIM to look up
Huntington's Chorea, and from the bottom of the OMIM document you can then
follow it to GDB (The Genome Data Base).  There you will find information
about locus "LD" on 4p16.3.  The information will be of probes, citations,
mutations, polymorphisms, DNAseq numbers (GenBank numbers), and even
mammalian homology information.  These can all be followed to greater and 
greater details of desquences, and contacts and so on.  If you have any
questions about this or any of the methods involved in doing searches
like this, feel free to contact me at "help at" for more information.

                          The Human Genome Database GDB(TM) 

                An international collaboration in support of the 
                         Human Genome Initiative hosted at 
                The Johns Hopkins University School of Medicine 
                              Baltimore, Maryland USA 

GDB (Genome Data Base)
GDB contains human gene mapping information.  The data are acquired by direct
submission to GDB, entry by Human Genome Organization (HUGO) editors, and by 
scanning of the scientific literature.  

GDB stores and curates the following types of information:

 . Loci          Defined regions of the genome, ranging in size between a
                 single point and an extended region.
 . Probes        Reagents for detecting genes, DNA segments and their 
 . Maps          Genetic or physical maps representing an ordered set of
                 elements (loci or probes) on a chromosome.
 . Polymorphisms Heritable variations in the DNA sequence of loci, often useful
		 in genetic mapping experiments.
 . Mutations     Spontaneous sequence variations in loci, often responsible for
                 clinical phenotypes.
 . Cell Lines    Clonal mammalian cell lines which are useful for genomic
                 mapping research.
 . Libraries     Collections of DNA clones, often from specific regions of the
 . Citations     Bibliographic citations (often with abstracts) for all GDB
                 data.  Citations in GDB include journal articles, books,
                 book chapters, meeting abstracts and personal communications.
                 The citation record also includes a list of linked GDB 
 . Contacts      Contact information for researchers involved in genome 
		 mapping, as well as GDB editors and staff.  The contact 
		 record includes name, address, phone and fax numbers and 
		 email address. When the contact has submitted clones, cell 
		 lines or libraries to GDB, these are also shown in the record.



The data stored in GDB are available electronically to the community through
the World Wide Web, e-mail, Gopher, WAIS, anonymous FTP, and SQL. 

o WWW (
     This enables hypertext searches of GDB.  Graphical WWW
     browsing software such as Netscape supports forms-based
     searching of GDB. Clients such as Lynx support text search only.

o E-mail searching (mailserv at
     Send searches via e-mail to above address.
     Put the word 'help' on a line by itself in the body of the message to
	receive the help file explaining how to search via e-mail.
     Requires only e-mail access (needs no additional software).

o Gopher (
     Use "keywords" to search GDB (as a whole or by data type).
     Requires a gopher client pointed at the above address.

     GDB is a source via Wide Area Information Servers.
     Requires WAIS client software.

o Anonymous FTP (
     Download data, documentation, software, output reports from GDB in

o SQL Server (
     Sybase server containing GDB tables for direct SQL query.
     Requires a Sybase license and registration. Contact GDB User Support
