CDH2 and cryptorchidism: Another syndrome with some of the features seen in this patient case is ACOGS, which is caused by a heterozygous mutation in the CDH2 gene and has been associated with corpus callosum agenesis or hypoplasia, developmental delay and intellectual disability, ocular findings, including strabismus and Duane anomaly, congenital heart defects, cryptorchidism, and craniofacial dysmorphisms such as a thin upper lip, hypertelorism, flat nasal bridge, and low-set ears [11].
