Forty-seven pathogenic variants causing autosomal recessive disorders are shared by Israeli and Saudi Arabian Arabs.

Abstract

Several autosomal recessive disorders that are found among Arabs in Israel were also reported in Saudi Arabia. In a sytematic review of all the variants responsible for autosomal recessive disorders among Muslim Arabs Israel and in Saudi Arabia, 47 shared variants were found, many being known founder variants in both populations. Among the 21 shared variants that were reported among Bedouins 14 were founder variants representing 14% founder/assumed founder variants known in the Bedouins. Many of the common variants are ancient having a Bedouin origin probably linked to the migration from the Saudi Peninsula. It is probable that a similar phenomenon occurred along the route of the Bedouin migrations and indeed some of these variants are present in the corresponding populations.
