Chromosome 22 and the location of Infantile cerebellar-retinal degeneration related ACO2 gene.
INFANTILE CEREBELLAR-RETINAL DEGENERATION(ICRD) is one of the rare neurodegenerative disorders affecting the brain and eyes.

The disease is derived from the defective ACO2 gene, causing hypotonia, seizures, athetosis, ophthalmologic abnormalities, and global developmental delay.

Infantile cerebellar-retinal degeneration is known to affect less than 1 in 1,000,000 worldwide.

The symptoms usually appear from the neonatal period to infancy.


Seven symptoms of INFANTILE CEREBELLAR-RETINAL DEGENERATION: Developmental delay and intellectual disability, Truncal hypotonia, Athetosis, Seizures, Optic atrophy, Retinal dystrophy, Hearing and vision loss
The main characteristic symptoms include degeneration of ophthalmologic and nervous systems.


The diagnosis of Infantile cerebellar retinal degeneration needs a team approach of a pediatrician, an ophthalmologist, and a neurologist.

After their clinical evaluation, a genetic test is necessary to confirm the causative genetic variant.
