Hereditary disorders in the Eastern Mediterranean Region.

Hereditary diseases and congenital malformations have been reported to affect 2-5% of all live births. Available evidence suggests that genetic disorders are equally important also in countries of the Eastern Mediterranean Region. Considerable achievements have been made over the last two decades in controlling communicable diseases in the region. Concurrently, there has been a mounting awareness of the increasing importance of hereditary disorders. Certain genetically determined diseases such as the haemoglobinopathies and enzymopathies are extremely common in the region and the need to initiate public health measures for their control is increasingly being recognized. The following factors may contribute to the elevated prevalence of genetically determined disorders: the high consanguinity rates; the high frequency of haemoglobinopathies and glucose-6-phosphate dehydrogenase deficiency; the trend of continuing to bear children up to menopause; the general lack of public awareness about genetic diseases; and the dearth of genetic services in the region. These and some other related issues are discussed in detail in this review article.
