To carry out genome-wide copy number variations (CNVs) analysis for a boy with autism by using single nucleotide polymorphism array (SNP array).


SNP array analysis was conducted for the boy and his parents, and the data was validated by real-time PCR. Correlation between the deleted genes and the phenotype was analyzed by reviewing the literature.


The patient was found to carry a terminal deletion of 18q22.3q23 (7.1 Mb), which involved FBXO15, ZNF407, ZADH2, TSHZ1, MBP and ADNP2 genes. No pathogenic CNVs were found in the parents. Comparison of the patient with cases reported in the literature suggested that the ZNF407 gene probably accounts for the autistic phenotype in these patients.


The autistic phenotype of the patient may be attributed to the 18q deletion, for which ZNF407 may be a critical candidate. SNP array has provided an useful tool for the study of molecular mechanism underlying autism.
