Genetic Disorders
Genetic Disorders is a disease that is caused by a change in the DNA sequence of an individual, or a mutation.
Genes are the minor segments of DNA in the nucleus of chromosomes. They act as blocks of inheritance. They pass from a parent to a child and control the biological features.
They have instructions for cellular activities to be regulated. The structure and number of genes (s) is sometimes affected by mutation.
Mutation modifies the instructions of the gene and the cells therefore do not function normally. This can cause a genetic disorder called a medical condition.
A disease caused by defects or changes in a person’s DNA is therefore a genetic disorder. In human beings, genetic disorders may be heritable or not. They are divided into two types: mendelian and chromosome disorders.
