The glial glutamate transporter complementary DNA in patients with amyotrophic lateral sclerosis

Here, we report a mutation screening by single-stranded conformational analysis of the astroglial human brain glutamate transporter (HBGT) II complementary DNA in patients with amyotrophic lateral sclerosis. The conformational analysis data indicate a lack of sequence variations in the HBGT II coding region in 6 patients with amyotrophic lateral sclerosis and the same number of nonneurological control subjects. In both groups, three variants of the HBGT II 5' untranslated region were isolated. We have no evidence that the reported complementary DNA variants are disease specific.
