A) Copy number analysis flanking CHRNA7 gene, with downward arrows indicating a deleted region in the patient and father just distal to CHRNA7 and upward arrows indicating the beginning of a duplicated region in mother. B) Copy number analysis flanking CHRFAM7A gene, with arrows indicating the beginning and the end of the duplicated region in the patient's mother.
