Genetic disorders can be caused by a mutation in one gene (monogenic disorder), by mutations in multiple genes (multifactorial inheritance disorder), by a combination of gene mutations and environmental factors, or by damage to chromosomes (changes in the number or structure of entire chromosomes.
Some examples of genetic disorders involving more than one defective gene are cystic fibrosis, which is caused by mutations in the CFTR gene and other modifier genes; and certain types of neurofibromatosis, which result from mutations in both the NF1 and NF2 genes. These disorders demonstrate the complexity of genetic inheritance and the interactions between multiple genes.
Hematology blood disorders can be caused by a variety of factors, including genetic mutations, autoimmune reactions, infections, medications, and environmental toxins. Some disorders, such as sickle cell anemia, are inherited, while others, such as leukemia, can be caused by a combination of genetic and environmental factors. In some cases, the exact cause of the disorder may be unknown.
Drinking or smoking during pregnancy can increase the risk of birth defects or developmental issues, but it does not directly cause genetic disorders in the baby. Genetic disorders are typically caused by changes or mutations in the baby's DNA that are inherited from the parents or happen spontaneously.
Some disorders of nucleic acids include: Genetic disorders caused by mutations in DNA such as cystic fibrosis, Huntington's disease, and sickle cell anemia. RNA-related disorders like myotonic dystrophy and fragile X syndrome, which are caused by abnormal expansion of nucleotide repeats in the gene. Defects in enzymes involved in nucleic acid metabolism can lead to disorders like Lesch-Nyhan syndrome or SCID (severe combined immunodeficiency).
Several genetic disorders are caused by genes on the X chromosomes.
If retardation is caused by chromosomal or other genetic disorders, it is often apparent from infancy.
Genetic disorders are not contagious because they are caused by changes in a person's DNA that are passed down from parents. They are not caused by germs, which are microorganisms like bacteria and viruses that can be transmitted from person to person.
Genetic disorders can be caused by a mutation in one gene (monogenic disorder), by mutations in multiple genes (multifactorial inheritance disorder), by a combination of gene mutations and environmental factors, or by damage to chromosomes (changes in the number or structure of entire chromosomes.
sickle cell anaemia, thalassaemia
Movement disorders caused by inherited genetic defects include Huntington's disease, spinocerebellar ataxias, dystonias, and certain forms of Parkinson's disease. These disorders result from specific genetic mutations that can be passed down from parents to their children. Symptoms may vary depending on the specific disorder but often involve involuntary movements, tremors, or muscle stiffness.
The medical term for a condition caused by defective genes is genetic disorder. These disorders are caused by abnormalities in an individualβs DNA and can result in a wide range of symptoms and health issues.

The majority of psychological disorders are thought to be caused by a complex combination of biological, genetic (hereditary), familial, and social factors or biopsychosocial influences.
x-linked recessive chromosome.
it can be..........it may result from autoimmune disorders that are hereditary.......
