Abstract
The Israeli population mainly includes Jews, Muslim and Christian Arabs, and Druze. Data on genetic diseases present in the population have been systematically collected and are available online in the Israeli national genetic database. Among the Israeli Arabs in December 31 2018, the database included molecular data on six diseases relatively frequent in the whole population: thalassemia, familial Mediterranean fever (FMF), cystic fibrosis, deafness, phenylketonuria or congenital adrenal hyperplasia as well as data on 632 autosomal recessive diseases among Muslim Israeli Arabs, 52 among the Christian Arabs and 79 among Druze. A single variant was characterized in 590 out of the 771 genes causing disorders in which the molecular basis was known. Many of the variants reported among Arabs in Israel are novels, most being found in one community only. Some variants are ancient and for instance, consistent with the migration history, several variants are found in the Bedouins from the Negev as well as from the Arab peninsula. In the 181 other disorders more than one variant was characterized either in the same gene or in more than one gene. While it is probable that most of these cases represent random events in some cases the reason may be a selective advantage to the heterozygotes.
