Figure 2From: Clinical and Molecular Characterization of Ataxia with Oculomotor Apraxia Patients In Saudi Arabia Ssequence chromatogram showing the region of exon 20 of SETX gene where the R2287X (c.6859 C > T) is located. (A) A normal control sequence trace homozygous for the normal allele (harbouring a "C" at position 6859). (B) The patient is homozygous for the mutant allele (harbouring a "T" at position 6859). Arrow points to the base substitution.Back to article page
