Of the practicing regions, Middle Eastern and northern Africa territories show the greatest frequencies of consanguinity.
[65]
Among these populations with high levels of inbreeding, researchers have found several disorders prevalent among inbred offspring. In
Lebanon,
Saudi Arabia,
Egypt, and in
Israel, the offspring of consanguineous relationships have an increased risk of congenital malformations, congenital heart defects, congenital
hydrocephalus and
neural tube defects.
[65] Furthermore, among inbred children in
Palestine and Lebanon, there is a positive association between consanguinity and reported
cleft lip/palate cases.
[65] Historically, populations of
Qatar have engaged in consanguineous relationships of all kinds, leading to high risk of inheriting genetic diseases. As of 2014, around 5% of the Qatari population suffered from hereditary hearing loss; most were descendants of a consanguineous relationship.
