Hereditary diseases are problems or illnesses which are inherited genetically. They are also known as genetic disorders or hereditary diseases and may be passed on in the family when there is a mutant gene present.
There are various genetic disorders which may be categorized into four: single gene, multifactorial, chromosomal and mitochondrial.
When one among the parents has a mutant gene and the other has a regular gene, the kid has fifty percent probability of inheriting the disorder.
Achondroplasia is an inherited disorder which causes an unusually short stature with disproportionately short limbs. Adults with achondroplasia might reach an average height of four feet. This birth defect happens due to the mutation of the FGFR3 gene and cannot be treated.
Hereditary hemochromatosis is a genetic illness that causes the body to soak up an excessive amount of iron. Absorbed iron does not leave the body, but instead it is stored within the body organs, which could cause many health problems. This condition causes delay in the physical and emotional development of a young child.
