Ellen McDonagh (Genomics England Curator)

Comment on list classification: All reports are for the same variant, in patients with Arab descent, therefore decided in the Analysis and Interpretation meeting to make this red for now as the finding has not been repeated with a seperated variant or in a seperate population.

Comment on list classification: 6 patients (2 were siblings) affected with infantile-onset neurodegenerative manifestations with severe leukodystrophy were homozygous for the c.G229A mutation in ISCA2.
