Some 906 genetic disorders have been identified in Arabs and their descendants, Several common diseases in the UAE, Oman and Bahrain have reached epidemic levels - more than 100 cases per 100,000. They include Thalassaemia (a blood disorder), Diabetes, Breast cancer and Down's syndrome. Some of the disorders have reached epidemic proportions like Sickle cell disorder, Heart diseases, Alpha Thalasemia, Diabitis Mellitus. Some of the main genetic diseases prevalent in Arab countries are hemoglobin disorders, birth defects, inherited metabolic diseases and neurogenetic disorder. hemoglobin disorders are sickle cell disease and thalassemia. Multiple pterygium syndrome, Down syndrome, microcephaly and Bardet-Biedl syndrome are examples of the disorders causing birth defects. Arab countries have the highest prevalence of birth defects in the world of neurogenetic disorders are Tourette's syndrome, Wilson's disease, Charcot-Marie-Tooth disease, mitochondrial encephalomyopathies and Niemann-Pick diseass

Genetic diseases Databases in Arabic countries
Several organizations maintain databases for each arabic country.

CAGS is the main organization based in UAE. CAGS or the Centre for Arab Genomic Studies initiated a pilot project to construct the "Catalogue for Transmission Genetics in Arabs" (CTGA) database for genetic disorders in Arab populations. At present, the CTGA database, centrally maintained in Dubai, hosts entries for nearly 1540 Mendelian disorders and related genes and this number is increasing as researchers are joining the largest Arab scientific effort to define genetic disorders described in the region. The Center promote research studies on the emergent disorders Some of the challenges are: Hemoglobinopathy sickle cell anemia Glucose-6-phosphate dehydrogenase deficiency favabeans chorionic villus sampling (CVS)amniocentesis Fragile X syndrome (FXS) is an inherited genetic condition with critical consequences The Centre provide information about specific countries http://cags.org.ae/publications.html and maintain alist of Genomic diseases   

Specific rare Autosomal recessive diseases are high in Arabic countries like Bardet Biedhl syndrome, Meckel syndrome, congenital chloride diarria, Sever Child Autos Recessive Muscular Dystrophy (scarmd ) Lysosomal storage diseasesand PKU are high in the Gulf states. Dr Teebi's book provides detailed informations by country http://www.voanews.com/content/study-indicates-merscov-is-not-yet-pandemic/1695502.html Even the Middle East respiratory syndrome coronavirus (MERS-CoV) was first identified in Saudi Arabia last year, it has infected 77 people, mostly in the Middle East and Europe. Forty of them - more than half - have died. But MERS is not yet a pandemic,could become pervasive in genetic disease patient.

Dr Thurman' guidebook about Rare genetic diseases The highest proportion of the genetic disorders are congenital malformations followed by endocrine metabolic disorders and then by neuron disorders and then by blood% immune disorders and then neoplasms. The Mode of Inheritance is mainly autosomal recessive followed by autodsomal dominant BETA-THALASSEMIA MUTATIONS; SICKLE-CELL DISEASE; CONGENITAL HEART-DISEASE; WESTERN SAUDI-ARABIA; GLUCOSE-6-PHOSPHATE-DEHYDROGENASE DEFICIENCY; ALPHA-THALASSEMIA; MOLECULAR CHARACTERIZATION; RECESSIVE OSTEOPETROSIS; CONSANGUINEOUS MARRIAGE; GLUTATHIONE-REDUCTASE DEf.

Genealogy and Geographic of Arabic genetic diseases:
Bare lymphocyte syndrome in high western Arabic block Morocco, type II Limb-girdle muscular dystrophy, type 2C in Lybia, Hemolytic-uremic syndrome in Saudia, Ankylosing spondylitis in Egypt &East block, Alpha-thalassemia in all countries minus egypt syria iraq, Cystic Fibrosis in iraq saudi yemen lybia morocco, Famylial Mideterranean Fevr fmf in east block and lybia morocco, beta Thalasemia in all countries, g6dh deficiency all countries.

Genetic studies on Arabs that lead to discoveries of New Syndromes
Teebi type of Hypertelorism (1987) •• Teebi--Shaltoutsyndrome (1989) •• Al--Gazalisyndrome (1994) •• Megarbane syndrome (2001)

There are even new Arabic names for emerging genetic disorders& syndromes like: Spectrum of Genetic Disorders in Arabs •• Lebanese type of mannose 6--phosphate receptor recognition defect (1984) •• Algerian type of spondylometaphyseal dysplasia(1988) •• Kuwaiti type of cardioskeletalsyndrome (1990) •• Yemenite deaf--blind hypopigmentation syndrome (1990) •• Nablus mask--like facial syndrome (2000) •• Jerash type of the distal hereditary motor neuropathy (2000) •• Karak syndrome (2003) •• Omani type of spondyloepiphy
