Studying the human genome to understand the risk of autism

A team of researchers at CHU Sainte-Justine and Université de Montréal has succeeded in using bioinformatics to develop a statistical model to assess how the gain or loss of genetic material impacts the risk of autism.

Is risk of Alzheimer's linked to specific sleep patterns?

Disturbed sleep patterns do not cause Alzheimer's disease but people who are at high genetic risk of developing Alzheimer's disease may be more likely to be a "morning person," have shorter sleep duration and other measures ...

Genetic disorder

A genetic disorder is an illness caused by abnormalities in genes or chromosomes. While some diseases, such as cancer, are due in part to a genetic disorders, they can also be caused by environmental factors. Most disorders are quite rare and affect one person in every several thousands or millions. Some types of recessive gene disorders confer an advantage in the heterozygous state in certain environments. A haploid cell has only one set of chromosomes. A diploid cell has two sets of chromosomes. In human, the somatic cells are diploid, and the gametes are haploid.

Genetic diseases are typically diagnosed and treated by geneticists. Genetic counselors assist the physicians and directly counsel patients.[citation needed]
