While the detection power of our array increases with the size of the variant, we would certainly miss smaller and intragenic CNVs, for example in autism candidate genes such as NRXN1[65], [66], CACNA1C, SLC4A10, MAGI1[63], SYNGAP1, DLGAP2[62], NLGN1, ASTN2[67], and exonic copy number variants in ASPM, DPP10, CNTNAP2, A2BP1, PCDH9[68], and PTCHD1[69]. Here, PCDH9 is linked to autism.
