Glutaric aciduria type I in the Arab and Jewish communities in Israel
- Shaare-Zedek Medical Center, Jerusalem (Israel); and others
Mutation analysis was performed in eight families (16 patients) with glutaric aciduria type I (GA-I), which were all the families diagnosed in Israel in the years 1987 - 1994. Six families were of Moslem origin and two were non-Ashkenazi Jews. The entire coding region of the cDNA of the glutaryl-CoA dehydrogenase gene was sequenced in one patient of each family. Seven new mutations were identified in 15 of 16 mutated alleles, including six point mutations: T4161 (4 alleles), G39OR (1 allele), and S305L, A293T, L283P, and G101R (2 alleles each). In addition, a 1-bp deletion at position 1173 was identified in two alleles. These findings do not provide a molecular basis for the clinical variability in GA-1 families. The occurrence of multiple novel mutations in a small geographic area may be explained by their recent onset in isolated communities with a high consanguinity rate. 22 refs., 3 figs., 3 tabs.
