Genetic Disorders are caused by abnormality in an Individuals DNA i.e. Genes and Chromosomes. Some diseases like Cancer are sometimes hereditary and partially occur due to Genetic Disorders various other factors are mostly the reason for Cancer. Human Genetics describes the study of inheritance or hereditary and has helped scientists in getting a better understanding of Genetic Disorders, genetic disorder symptoms or chromosomal abnormalities and how they are related to hereditary.

Genes are considered to be the common factor of most of the hereditary traits found in humans and the study of human genetics has helped understanding the human nature, disease and work on an effective treatment for the same. The ongoing genetic research after careful study of human genetics has resulted in amazing breakthrough in treatment of Genetic Disorders and has helped minimize genetic disorder symptoms. However most people refer to Genetic Disorders as hereditary diseases and study of Human Genetics has proved that many genetic disorders are not necessarily hereditary but various other environmental factors and other reasons can lead to Genetic disorder. |
Human Genetics Study has also proved that Genetic disorders due to chromosomal abnormalities are usually caused due to an accident in the egg or sperm and result in distorted chromosome which is refereed as chromosomal abnormality, for example a person suffering from Down Syndrome a form of genetic disorder will have three copies of chromosomes rather than two whereas in Turner Syndrome the individual has only one sex chromosome these are forms of numerical chromosomal abnormality.
Structural chromosomal abnormality also causes genetic disorders which can be due to deletion, duplication, translocation or inversion of the chromosomes or part of it and examples of genetic disorder due to structural chromosomal abnormality are Wolf-Hirschhorn Syndrome,Charcot Marie Tooth Disease type 1A etc.
Chromosomal abnormalities and hereditary go hand in hand for most of the genetic disorders. The study of Human genetics today has not only helped many who are suffering from genetic disorders but has also helped many to be successfully treated for genetic disorder symptoms. Careful research and study of the complex human body, chromosomes and genes has helped the doctors and scientists to ease the pain of families and individuals suffering from genetic disorders and have lowered the risk of theses genetic disorders from being passed on to the next generation. Awareness towards such diseases and its symptoms can help curb down the risk of permanent ailment. |
