The congenital genetic disorders in babies occur due to the mutated or altered gene, which passes from the parents to the baby. The congenital disorders are those that exist at birth. The congenital genetic disorders result from genetic abnormalities. The genetic imbalance gives rise to the fertilized egg with either too much or too little genetic information.
The babies with congenital genetic disorders have errors in gene. During the formation of egg or sperm, the genetic errors occur. For those parents who have a baby with genetic abnormality should consult a doctor to know the causes of genetic disorders and the chances of recurring in another pregnancy.
In case of genetic disorders in babies, the variation or mutation of gene takes place. The mutation or alteration of gene takes place due to different reasons, among which the environmental exposures to cigarette smoke is one. In case of congenital genetic disorders, the child inherits the genetic disorder from parents. Moreover, he is born with the signs and symptoms of genetic defects.
In case of congenital genetic disorders, the mutated or altered gene (responsible for the genetic defects) is passed down and there is a chance that each generation of children will inherit the disorder-causing gene. The other genetic problems occur due to errors in an entire chromosome or part of a chromosome.
During the case of chromosomal error, the error occurs when the egg or sperm is being formed. During this time, usually a chromosome is broken or missed or an extra chromosome is present. During the development of an embryo, the cells go through the division process and the additional or missing genetic information results into abnormal body structures as well as abnormal body functions.

The genetic defects in babies can cause mental retardation and several other defects including the disorder of heart and kidney. Some of the very common genetic disorders are Down syndrome, cystic fibrosis, sickle cell disease Tay-Sachs disease, spina bifida, etc.
The diseases like Marfan syndrome, Huntington's disease, etc. can be inherited from just one parent while the diseases like cystic fibrosis, Tay-Sachs disease, sickle cell anemia, cannot be inherited unless both the mother and father pass along the gene. The common genetic defects like Down syndrome is usually not inherited and results from mutation in the cell division process. Achondroplasia occurs due to genetic mutation and sometimes it is inherited.

A number of prenatal tests are available today, which can help you to predict any potential health risk and assess the health of the mother and the baby. The genetic testing can identify the chances of passing certain genetic diseases or disorders to your children.
