Cavitating and tigroid-like leukoencephalopathy in a case of NDUFA2-related disorder.

Biallelic variants in nuclear gene NDUFA2 have been reported so far in only three children with variable presentations including Leigh syndrome or leukoencephalopathy. Herein, we report a further female child affected by NDUFA2-related disorder presenting with cavitating and tigroid-like pattern of leukodystrophy and without systemic biochemical abnormalities of mitochondrial disorders.
