Genetic Counselling

The area of health care that offers advice on genetic problems is called genetic counselling (a term first introduced by Sheldon Reed in 1940)

Genetic counselling helps individuals or families understand the chances of inherited disorders, the methods available for diagnosis, and the possible medical and reproductive choices before or during pregnancy.​ It combines genetic knowledge with biochemical, statistical, and physiological approaches to identify risks and support informed decision-making.

Genetic counselling is especially useful for the following groups:​

• Couples with a family history of genetic disorders.​
• Parents who already have a child with a birth defect or inherited disease.​
• Older parents, especially where the risk of chromosomal abnormalities may increase.​
• Couples with repeated abortions or repeated pregnancy loss.​
• People from families or communities where inherited disorders such as sickle-cell anaemia are found.​
• Couples in consanguineous marriages, where the chances of recessive disorders may rise.

Genetic counselling may involve the following methods and related tools:​

• Study of family history and pedigree pattern.​
• Biochemical and physiological testing for inherited conditions.​
• Statistical assessment of genetic risk.​
• Prenatal diagnostic methods, such as amniocentesis.​
• Use of laboratory techniques to identify chromosomal or genetic abnormalities in the foetus.

• Explains the nature and inheritance pattern of a genetic disorder.​
• Estimates the probability of a disorder occurring in the child.​
• Suggests appropriate screening or diagnostic tests.​
• Helps families understand reproductive choices in a scientific and responsible way.​
• Supports the prevention or early detection of genetic and sex-linked disorders.​
• Assists in informed family planning decisions.

• Prenatal techniques may reveal the sex of the fetus.​
• Misuse of sex determination for sex selection is socially harmful.​
• Such misuse can disturb the sex ratio in society.​
• Therefore, students should clearly distinguish between medical diagnosis and unethical sex selection practices.​

Genetic counselling is meant for informed medical guidance, not for promoting sex selection.

• Genetic counseling helps individuals understand the risks and implications of hereditary conditions by analyzing family history and medical data.
• It primarily assists high-risk groups, such as those with a family history of genetic disorders or prospective parents of advanced age, through tools like pedigree analysis and amniocentesis.
• Beyond diagnosis, it provides essential guidance on reproductive choices and the management of inherited diseases.
• Crucially, the process must remain ethically grounded, focusing strictly on medical health rather than prohibited practices like sex determination.
• This support enables families to make informed, science-based decisions about their future.
