While the number of ASD probands with MEMO1 variants, identified to date, is relatively small, copy number variation (CNV) databases such as DECIPHER [79], reveals additional individuals with deletions or duplications of regions encompassing MEMO1.

This evidence concerns the gene MEMO1 and autism.
