β¦ Synopsis
The L1 syndrome is an X-linked recessive disease caused by mutations in the L1CAM gene. To date more than 200 different mutations have been reported, scattered over the entire gene, about 35% being missense mutations. Although it is tempting to consider these missense mutations as being disease-causing, one should be careful in drawing any firm conclusions, unless there is additional supporting information. This is in contrast to truncating mutations, which are always considered to be disease-causing, unless they involve truncations close to the gene stop codon. In order to allow conclusions to be drawn on the disease-causing nature of L1CAM (missense) mutations, we have updated and upgraded our LICAM mutation database with more pathogenicity data and clinical information collected from the literature or generated by our own research. As a result, the renewed database offers condensed scientific information, allowing conclusions to be drawn on the pathogenicity and severity of LICAM mutations based on multiple factors. The L1CAM Mutation Database is at: www.l1cammutationdatabase.info.

## Communicated by Marc Greenblatt Recently, a novel exon was described in TCOF1 that, although alternatively spliced, is included in the major protein isoform. In addition, most published mutations in this gene do not conform to current mutation nomenclature guidelines. Given these observations,
L1 disease is a group of overlapping clinical phenotypes including X-linked hydrocephalus, MASA syndrome, spastic paraparesis type 1, and X-linked agenesis of corpus callosum. The patients are characterized by hydrocephalus, agenesis or hypoplasia of corpus callosum and corticospinal tracts, mental
