The Complexity of Making a Diagnosis

CASE: Carl is a 12-year-old boy midline, with neurologic malformation, ataxia, bilateral strabismus with presumed residual visual impairment after surgical repair, and intellectual disability. He was referred to developmental-behavioral pediatrics for evaluation of possible autism spectrum disorder (ASD). Carl had a benign prenatal course and was born via spontaneous vaginal delivery at term. Bilateral strabismus was noted at birth. Despite surgery to address strabismus, Carl continues to be unable to raise his eyes above midline, and his visual status, including visual acuity, depth perception, color perception, and visual fields, is unclear. A recent auditory brainstem response evaluation was consistent with normal hearing. Multiple variants of undetermined significance were reported on chromosomal microarray. Magnetic resonance imaging of the brain demonstrated multiple malformations in the brainstem and posterior fossa. Electroencephalogram was without evidence of seizure activity. There is no family history of genetic disorders, brain malformation, or learning/cognitive disability. Carl was not able to sit independently until 2 years of age and did not walk until 5 years. Now, he can walk short distances by himself but is often unsteady on his feet. He uses a wheelchair but does not propel himself despite a physical therapy assessment indicating that he has adequate strength to do so. Carl spoke his first word at 5 years, and his parents report that he currently uses...
