KIAA0319 Antibody – Goat Polyclonal

This gene encodes a transmembrane protein that contains a large extracellular domain with multiple polycystic kidney disease (PKD) domains. The encoded protein may play a role in the development of the cerebral cortex by regulating neuronal migration and cell adhesion. Single nucleotide polymorphisms in this gene are associated with dyslexia. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene.

KIAA0319: Involved in neuronal migration during development of the cerebral neocortex. May function in a cell autonomous and a non- cell autonomous manner and play a role in appropriate adhesion between migrating neurons and radial glial fibers. May also regulate growth and differentiation of dendrites. Defects in KIAA0319 may be a cause of susceptibility to dyslexia type 2 (DYX2); also known as specific reading disability type 2. Dyslexia is a relatively common, complex cognitive disorder that affects 5% to 10% of school-aged children. The disorder is characterized by an impairment of reading performance despite adequate motivational, educational and intellectual opportunities and in the absence of sensory or neurological disability. A lower expression is associated with the risk haplotype. 3 isoforms of the human protein are produced by alternative splicing.
