Osteopetrosis and infantile neuroaxonal dystrophy

(OMIM phenotype number #600329)

Osteopetrosis and infantile neuroaxonal dystrophy is characterized by osteopetrosis, agenesis of the corpus callosum, cerebral atrophy and a small hippocampus. There are rare cases reported with the association of neuroaxonal dystrophy and osteopetrosis. Autosomal recessive inheritance has been suggested and the etiology remains unclear.
