Last updated: 10 Feb 2011

Name: Aicardi syndrome

Mode of Inheritance: XLD

OMIM number: 304050  


AIC#, mapped to Xp22

Tumor features

choroid plexus papilloma

Tumor features (possible)

colorectal polyps
gastric polyps
palate, benign teratoma of
parapharyngeal embryonal cell cancer

Non-tumor features

chorioretinal lacunae
cleft lip
cleft palate
corpus callosum agenesis
developmental delay/mental deficiency/mental retardation
facies, asymmetric
gross motor delay
rib anomalies
vertebral anomalies


Clinical hallmarks are infantile spasms, corpus callosal agenesis, chorioretinal abnormalities (lacunae) and severe psychomotor retardation. Other findings include plagiocephaly, facial asymmetry, cleft lip and palate and costovertebral anomalies. A number of tumors have been reported in association with Aicardi syndrome: choroid plexus papilloma is the most frequent tumor[5,6,10], medulloblastoma[7], gastric hyperplastic polyps[1], rectal polyp[1], soft palate benign teratoma[1], hepatoblastoma[4], parapharyngeal embryonal cell cancer[2], angiosarcoma[3,9] and scalp lipoma[3].
