Consanguineous marriage is an important social phenomenon، as it is closely related to the prevailing social customs and values of societies. Consanguineous marriage and the most common hereditary diseases in the eastern region of Libya، where samples were collected through Al-Ishraqa School in Al-Bayda city and conducting some interviews with the patients’ families and reviewing the medical reports and family history. The study was conducted on 21،351 cases collected from some Libyan cities from 2003 to 2010. Through it، identifying some of the reasons that help the emergence of genetic diseases، whether the reason is the marriage of relatives or because of external influences، where the total percentage showed the presence of congenital malformations 3%، mental retardation 26%، the blind 2%، the deaf and dumb 5%، and the hard of hearing 15%، muscular dystrophy 1%، multi-disability 4%، and other diseases 44%، and we discussed a statistical study on mental retardation and its relationship to inbreeding، and we found clear moral differences between males and females. Where the percentage of infection among males was higher than females، and the highest percentage of infection was in the city of Al-Marj 40%، followed by Al Bayda 35%، then Al-Qubba 14% and Shahat 11%، and the years were compared and there was a high rate increase in 2010 estimated at 21% compared to in 2003 0.5%، After analyzing the data، we reached the requirement of premarital examination for consanguineous married couples and spreading cultural awareness of the dangers of consanguineous marriage.
