MASA syndrome Classification and external resources OMIM 303350 MASA syndrome, also called CRASH syndrome and Gareis-Mason syndrome,[1] is a rare X-linked recessive[2] neurological disorder.
The acronym "MASA" describes the four major symptoms - Mental retardation, Aphasia, Shuffling gait, and Adducted thumbs.[3] The disorder has been associated with mutations in the L1CAM gene.[4] (The term "CRASH", for "corpus callosum hypoplasia, retardation, adducted thumbs, spastic paraplegia, and hydrocephalus" has also been used to describe L1CAM-related disorders.)[5]
