Summary Information
A duplication of this region of unknown origin was identified in a patient born to consanguineous parents that presented with 18q Syndrome (intrauterine growth restriction, failure to thrive, microcephaly, developmental delay, recurrent infections, small anterior fontanelle, strabismus, elevated palate, resolved laryngomalacia, atrial septal defect,and bilateral cryptorchidism) (Al-Qattan et al., 2014).
