Overlapping idications

• R271 Neuronal ceroid lipofuscinosis type 2 test should be considered where clinical features are specific to CLN2 • It is anticipated that many specific metabolic diagnoses will be made through use of broad genomic testing via the R98 Likely inborn error of metabolism - targeted testing is not possible early in the investigative pathway and in cases with atypical features where a broader differential diagnosis is under consideration
