Purpose:
To report a case of a unilateral retinal cavernous hemangioma associated with a novel splice-site mutation in CCM1/KRIT1.
Methods:
An 11-year-old girl was noted to have an asymptomatic retinal cavernous hemangioma in the left eye. CCM1/KRIT1 was screened for mutations.
Results:
Genetic evaluation of CCM1/KRIT1 revealed a single guanine-to-cytosine transversion in the invariant splice acceptor consensus sequence of intron 8 (c.1146-1G-->C), which is predicted to result in abnormal protein splicing.
Conclusions:
Mutations in CCM1/KRIT1 may be found in asymptomatic patients with retinal cavernous hemangioma.

The Retinoblastoma Gene
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...
