其他：Children with reading disability
Children with NF1, with reading disability if their performances on reading assessment (Alouette Test) present a delay of at least 18 months, will have Neuropsychological assessments, morphological and functional MRI (fMRI) and genetic analysis
|
IQ (WISC-IV) Reading tests (reading accuracy, reading speed, reading comprehension and strategy): Alouette, Lobrot, Odedys tests. Visuo-spatial skill (JLO, Thurston, CORSI tests) Attention (CPT 2, CBCL) Receptive oral language (EVIP)
The fMRI will consider on the acquisition of a 3D anatomical sequence in T1 high resolution in axial slices of 1mm with an acquisition time of 10 min and a T2 sequence and a "Flair" to allow UBO location.
Blood collection in 3 tubes (2 PAXgen® and 1 EDTA) and analysis to study the NF1 gene deletion.

其他：Children without reading disability
Children with NF1, without reading disability if their performances on reading assessment (Alouette Test) present a less than 18-month delay, will have Neuropsychological assessments, morphological and functional MRI (fMRI) and genetic analysis.
