Intracranial Calcifications and Ocular Abnormalities in a Child with Neurodevelopmental Delay

A patient with neurodevelopmental delay and an unremarkable prenatal and birth history presented postnatally with congenital cataracts and neuroanatomical abnormalities including periventricular calcifications, porencephaly, and cerebellar hypoplasia. Although there was initial suspicion for a TORCH infection including cytomegalovirus, further genetic testing revealed a novel COL4A1 mutation, which involves type 4 collagen alpha 1 chain, an important component of vasculature.
