- 2. DEFINITION In clinical genetics, a consanguineous marriage is defined as a union between two individuals who are related as second cousins or closer.
- 8. REASONS FOR CHOOSING TO MARRY A COUSIN • Consanguinity is a deeply rooted cultural trend in certain communities. • More favourable for the women`s status. The wife would have better relationship with her in-laws and could be protected by them in time of need. • There is a general belief that marrying within the family reduces the possibilities of hidden health and financial uncertainties.
- 9. REASONS FOR CHOOSING TO MARRY A COUSIN • Premarital negotiations regarding financial matters of marriage are more easily conducted, keeping the money and property within the family. • Strengthens family ties, and enforces family solidarity.
- 10. FACTORS AFFECTING CONSANGUINITY RATES • Consanguinity rates are higher in rural than urban settings of a certain community. • Higher female education reduces the rate of first cousin marriages. • First cousin marriages are more common when the parents of the couple are consanguineous.
- 11. FACTORS AFFECTING CONSANGUINITY RATES • In the same community, consanguinity rates are higher among Muslims than among Christians, for example in Lebanon, Jordan, South India.
- 12. FACTORS MAY DECREASE CONSANGUINITY RATE • Higher female education • Higher age at marriage • Low fertility • More mobility from rural to urban • Better economic status of families
- 13. EFFECT OF CONSANGUINITY • Stillbirth rates are either similar or slightly higher among consanguineous couples than the non-related couples. • There is a positive association between parental consanguinity and increased infant and childhood mortality. • Many studies have shown a positive association between parental consanguinity and congenital heart defects. • The association of consanguinity with cleft lip and palate, and neural tube defects is not clear.
- 14. EFFECT OF CONSANGUINITY • Among genetic disorders, only autosomal recessive disorders are strongly associated with consanguinity. • The association of NCD’s ( such as diabetes, hypertension) with parental consanguinity is still not clear.
- 15. COUNSELLING • Genetic counselling is the process by which clients or their relatives, at risk of an inherited disorder, are advised to prevent, avoid or ameliorate the disorder. • They are advised on • the consequences and nature of the disorder, • the probabilities of developing or transmitting it, • the choices open to them in management and planning of their families.
- 16. COUNSELLING Genetic counsellors provide useful information and support to families who may be at risk of inherited disorders. • They are involved • in identification of families at risk • investigation of problems presented by the family • interpretation of information about the disorder • analysis of inheritance patterns and • evaluation of risks of recurrence • reviewing testing options available to the family.
