Fig. 3From: Neuronal intranuclear inclusion disease presented with recurrent vestibular migraine-like attack: a case presentationGenetic analysis of the NOTCH2NLC gene in the patient. On RP-PCR, the patient panel shows a saw-tooth tail pattern indicating an abnormal expansion more than 60 repeats (A), while control panel shows no repeat expansion in an unaffected individual (B). On fluorescence AL-PCR, expanded allele had an unusual peak at around 400 bp (C), while non-expanded allele had peak at around 240 bp (D)Back to article page
