Genes affected

KIAA0319 (HGNC:21580): (KIAA0319) 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.

Collection Method: clinical testing

The c.3034A>G (p.K1012E) alteration is located in exon 20 (coding exon 19) of the KIAA0319 gene. This alteration results from a A to G substitution at nucleotide position 3034, causing the lysine (K) at amino acid position 1012 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
