Genetic Diseases and Disorders

Submit Abstract Register Now

Genetic disorders may occur due to hereditary, passed down from the parents' genes. In other genetic disorders, defects may be caused by new mutations or changes to the DNA structure. In such cases, the defect will only be passed down if it occurs in the genetic line. The twin disease, such as some forms of cancer, may be caused by an inherited genetic condition in some people, by new mutations changes in other people, and mainly by environmental causes in other people. A genetic disorder is a genetic problem caused by one or more rare abnormalities in the genome, especially a condition that is present from birth conditions (congenital). Most genetic disorders are often rare and affect one person in every several thousands or millions. A single-gene disorder is involving a single mutated genetic condition. Over 4000 human diseases are caused by single-gene faults. Single-gene disorders or syndromes can be passed on to subsequent generations in several ways. Genomic imprinting develops anduniparental disomic, however that may affect inheritance patterns. The rare divisions between recessive and dominant types are not quite even "hard and fast", although the divisions between autosomal associated with X-linked types are involving since the latter types are distinguished purely based on the chromosomal location of the gene.
