1) meet the Definite diagnostic criteria for the ATR-X syndrome
2) Age > 2 years at the time of enrolment
3) Weigh 10 kg or more at the time of enrolment
4) Have a parent or reliable carer
5) Have given written consent to participate in this clinical trial. (If the patient is under 18 years of age, consent should be obtained from the individual and his/her legal guardian). If the patient's intellectual disability makes it difficult to obtain consent from the individual, consent should be obtained from the legal guardian.

2) Those with serious complications (e.g. haematological, renal, hepatic, cardiac, cancer)
3) Those with a history of major illness or surgery in the past, which is judged to affect the assessment of central nervous system function
4) Those with no visual function that allows recognition of test indices
5) Those with concomitant or previous history of photosensitivity or porphyria
6) With a history of hypersensitivity to 5-ALA, porphyrins or iron preparations
7) Those with haemochromatosis
