Summary

Excerpted from the GeneReview: 16p12.2 Microdeletion
16p12.2 microdeletion is characterized by variable clinical findings that do not constitute a recognizable syndrome. Of note, the significant bias in ascertainment of individuals undergoing clinical chromosomal microarray analysis (i.e., children with intellectual disability and developmental delay; individuals with schizophrenia) makes it difficult to accurately associate specific phenotypes to the 16p12.2 microdeletion. Findings commonly observed in children (probands) with this deletion include: developmental delay, cognitive impairment (ranges from mild to profound), growth impairment (including short stature), cardiac malformations, epilepsy, and psychiatric and/or behavioral problems. Other findings can include: hearing loss, dental abnormalities, renal and genital anomalies (the latter in males), and cleft palate ± cleft lip.
