= a genetic disorder is an illness caused by abnormalities in genes or chromosomes, and some genetic disorders are passed down from the parents genes, but others are always or almost and always caused by new mutations or changes to the DNA. A single gene disorder is the result of a single mutated gene. There are estimated to be over 4000 human diseases caused by single gene defects. genetic diseases can be inherited because they are mutations in the germ of the cell of the body and the cells involved in passing genetic information from parents to offspring.genetic diseases can also result from changes in DNA in somatic cells, or cells in the body that are not cells.Some genetic diseases are called Mendelian disorders they are caused by mutations that occur in the DNA sequence of a single gene. Genes code for proteins, the molecules that carry out most of the work, perform most life functions, and make up the majority of cellullar structures. A genetic disease is due to a faulty gene or group of genes. While not all gene defects cause disease, many do. New genetic diseases are discovered every month; as of 2001, there are estimated to be approximately 1,100 genetic diseases.= = = = =
