Abstract

ABSTRACT: We describe a child from a consanguineous family born with a rare autosomal recessive disorder affecting junctional adhesion molecule 3 (JAM3) causing profound neurological and ophthalmological injury known as haemorrhagic brain destruction, subependymal calcifications, and congenital cataracts (HDBSCC; MIM# 613730). She was the product of an unremarkable pregnancy and was born near to term but was noted shortly after birth to have congenital cataracts, poor vision, increased muscle tone, seizures, and developmental delay. Her older sister had an identical syndrome and had previously been documented to have homozygous mutations in JAM3 . Examination in our patient, although difficult because of bilateral central cataracts, revealed very poor vision, attenuated retinal vessels, optic atrophy, and a retinal haemorrhage in the right eye, implying that abnormal development of the retinas and/or optic nerves may at times play a significant role in the poor vision noted in children with HDBSCC.
