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.

Ambry Genetics

Sep 29, 2023

The c.2759A>G (p.H920R) alteration is located in exon 18 (coding exon 17) of the KIAA0319 gene. This alteration results from a A to G substitution at nucleotide position 2759, causing the histidine (H) at amino acid position 920 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
