Rare Genomics Institute - giving free genomic solutions to people affected by rare diseases

An estimated 250 million people worldwide suffer from rare diseases. However, because each individual disease affects such a small number of people, little funding is used to study these conditions. Consequently, these patients are left with neither hope of a cure nor understanding of the disease. Each day is a living struggle for them to find a social identity in a world where they feel socially neglected and lost. Because most rare diseases are genetic in nature, it is believed that genome sequencing has the power to help these patients in a way that conventional diagnostics cannot. However, most families affected with rare diseases are under financial strain, making access to such technologies difficult. To address this need, an institute called Rare Genomics Institute has been established.

For the First time, genome of a polar alga, Coccomyxa subellipsoidea, sequenced fully.


Life is diverse and life exists in every part of the earth including the most extreme habitats. One such extreme habitat is the polar regions. There is poor understanding of the adaptive mechanisms used by polar organisms to function under extreme cold conditions.  More than 30 psychrophylic microbial genomes have been fully sequenced and these  Psychrophilic prokaryotes were found to possess various adaptive strategies for survival in cold environments, including cold-induced desaturation of fatty acids in membrane lipids, protective mechanisms against increased amounts of solubilized oxygen and ROS, synthesis of antifreeze lipoproteins and glycoproteins, and global change in amino acid composition of encoded proteins to decrease protein structural rigidity.

For the first time  the genome of  a polar eukaryotic  unicellular green alga  Coccomyxa subellipsoidea (C169) has  been sequenced by  a team of  Researchers from  Mediterranean Institute of Microbiology (France), University of Nebraska (USA)  DOE Joint Genome Institute (USA), University of Rostock (Germany), Hiroshima University (Japan) and Georgia Tech Center for Bioinformatics and Computational Genomics (USA).

Analysis of the 48.8 MB genome of this alga (for comparison (approximate ): Human genome size-3000 mb, E.coli genome size 4.5 MB, Rice genome size 370 MB) revealed that like the psychrophylic  microbes sequenced, this eukaryotic alga is also possessing special features

How many genes in Tomato ?

Tomato Genome Update-1:

  • The genome size of tomato is ca. 900 MB (Approximate values: Human genome is 3000 MB, rice genome is 370 MB, Arabidopsis genome  is 130 MB, E.coli genome is 4.5 MB)
  • Total number of protein coding genes: 34,727 (8615 groups common between rice, Arabidopsis, grape, tomato and potato; 1727 groups are common between

Breaking Discovery: Tomato genome sequenced

The genome of tomato (Solanum lycopersicum),  a major crop plant and a model system for fruit development,  is sequenced by an International Consortium of Scientists. The genome of   domesticated tomato and  its closest wild relative, Solanumpimpinellifolium were sequenced.  The two tomato genomes show only 0.6% nucleotide divergence and signs of recent admixture, but show more than 8% divergence from potato, with nine large and several smaller inversions. In contrast to Arabidopsis,

Million Genomes by 2014

Without a doubt the hottest company in the genomics sector right now is gene sequencing powerhouse Complete Genomics. In just the last four years the company has come out of nowhere to dominate the market for low cost sequencing of human genomes in large quantities. Although Complete Genomics is now slated to sequence an incredible 5,000 human genomes in 2010, this is nothing compared to what the company has in store for the years ahead.  Just days ago, in a Singularity Hub exclusive interview with Complete Genomics CEO Dr. Cliff Reid, we have learned that the company is now hoping to sequence 50,000 genomes in 2011 and a whopping 1 million genomes by 2014.
