Mendelian or monogenic disorders are the kind of genetic disorders in humans that arise from a mutation in a single gene these disorders run in families and can be autosomal or sex-linked depending whether the affected gene is located on autosomes or sex chromosomes, and they can also be dominant or recessive depending if one or two alleles are necessary to develop the disorder.

Introduction genetic disorders are diseases that result from a change in the normal dna sequence most genetic disorders are caused by multifactorial means, involving a combination of genetic and environmental factors. This genetic information is located on the gene and this gene you can find on the chromosome each chromosome contain 2 copies of the gene we also call the “alleles” this allele will determine the phenotype of our behavior, and this behavior and the phenotype can transmit from the parents to.

Genetic diseases can also arise naturally via genetic mutations, which is presumably how the diseases arose in the first place hence, rare cases of genetic diseases are possible even if neither parent has any genetic history of the particular disease. Specific genetic disorders many human diseases have a genetic component some of these conditions are under investigation by researchers at or associated with the national human genome research institute (nhgri) below is a list of selected genetic, orphan and rare diseases.
Introduction genetic association studies test for a correlation between disease status and genetic variation to identify candidate genes or genome regions that contribute to a specific disease. Genetic tests are done by analyzing small samples of blood or body tissues they determine whether you, your partner, or your baby carry genes for certain inherited disorders genetic testing has developed enough so that doctors can often pinpoint missing or defective genes the type of genetic.
