This study investigated the effect of Arabic vowels on the reading comprehension of native Arabic speakers. This issue has not been addressed yet. Two groups of native Arabic speakers were randomly sampled, one from two elementary schools in the Haifa area, and the other from two elementary schools in Nazareth. Both groups in both experiments read Arabic texts in two reading conditions, vowelized and unvowelized; the older group (n = 74) answered 10 multiple-choice comprehension questions about each story, and the younger group (n = 71) answered seven multiple-choice comprehension questions. The results revealed that vowels were a significant facilitator of reading comprehension in both age groups. Considering these results, reading in Arabic orthography is not an autonomous word recognition process. An alternative approach is suggested for reading Arabic.
Based on a genomic search for linkage, a locus contributing to type 1 diabetes in a large Bedouin Arab family (19 affected relatives) maps to the long arm of chromosome 10 (10q25; nonparametric linkage = 4.99; P = 0.00004). All affected relatives carry one or two high-risk HLA-DR3 haplotypes that are rarely found in other family members. One chromosome 10 haplotype, the B haplotype, was transmitted from a heterozygous parent to 13 of 13 affected offspring compared to 10 of 23 unaffected siblings. Recombination events occurring on this haplotype place the susceptibility locus in an 8-cM interval between markers D10S1750 and D10S1773. Two adjacent markers, D10S592 and D10S554, showed evidence of linkage disequilibrium with the disease locus. A 273-bp allele at D10S592 was transmitted to 8 of 10 affected offspring compared to 3 of 14 unaffected siblings, and a 151-bp allele at D10S554 was transmitted to 15 of 15 affected offspring compared with 10 of 24 unaffected siblings. D10S554 and D10S592 and the closest flanking markers are contained in a 1,240-kb yeast artificial chromosome, a region small enough to proceed with positional cloning.
