Washington University Finishes Human Chromosome 7 Sequencing

NEW YORK, July 9 – The Genome Sequencing Center of the Washington University School of Medicine in St. Louis has completed its sequencing of human chromosome 7, and the findings will be published in tomorrow's issue of the journal Nature .

The chromosome, the largest of some five sequenced so far, has 1,150 gene and 940 “pseudogenes” and a relatively centrally located centromere, which divides the chromosome into a short arm and a long arm, according to a statement issued by the university. Sequencing was done from each end in the direction of the centromere, which contains many short repetitive DNA sequences and few, if any, genes.

Researchers Develop Polygenic Risk Scores for Dozens of Disease-Related Exposures

With genetic data from two large population cohorts and summary statistics from prior genome-wide association studies, researchers came up with 27 exposure polygenic risk scores in the American Journal of Human Genetics.

US Survey Data Suggests Ancestry Testing Leads Way in Awareness, Use of Genetic Testing Awareness

Although roughly three-quarters of surveyed individuals in a Genetics in Medicine study reported awareness of genetic testing, use of such tests was lower and varied with income, ancestry, and disease history.

Coral Genome Leads to Alternative Amino Acid Pathway Found in Other Non-Model Animals

An alternative cysteine biosynthesis pathway unearthed in the Acropora loripes genome subsequently turned up in sequences from non-mammalian, -nematode, or -arthropod animals, researchers report in Science Advances.
