The gene is located on the short arm of chromosome 3 (3p26.3). It is a single copy gene within the Watson (plus) strand, 957,399 bases in length and encodes a protein of 1026 amino acids (molecular weight 113.454 kDa)
Clinical relevance
Abnormal expression of this gene has been implicated in some cases of autism.[8] It has also been associated with cerebellar degeneration in spinocerebellar ataxia type 16.
