Summaries for Hydrocephalus Due to Congenital Stenosis of Aqueduct of Sylvius

About this section
NIH Rare Diseases : 53 Hydrocephalus due to congenital stenosis of aqueduct of sylvius (HSAS) is a form of L1 syndrome, which is an inherited disorder that primarily affects the nervous system. Males with HSAS are typically born with severe hydrocephalus and adducted thumbs (bent towards the palm). Other sign and symptoms of the condition include severe intellectual disability and spasticity. HSAS, like all forms of L1 syndrome, is caused by changes (mutations) in the L1CAM gene and is inherited in an X-linked recessive manner. Treatment is based on the signs and symptoms present in each person.

MalaCards based summary : Hydrocephalus Due to Congenital Stenosis of Aqueduct of Sylvius, also known as aqueductal stenosis, is related to congenital hydrocephalus and hydrocephalus, and has symptoms including muscle spasticity An important gene associated with Hydrocephalus Due to Congenital Stenosis of Aqueduct of Sylvius is L1CAM (L1 Cell Adhesion Molecule), and among its related pathways/superpathways are Neuroscience and Neural Stem Cell Differentiation Pathways and Lineage-specific Markers. The drugs Acetazolamide and Natriuretic Agents have been mentioned in the context of this disorder. Affiliated tissues include brain, testes and pineal, and related phenotypes are macrocephaly and agenesis of corpus callosum
