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.

The c.2572C>T (p.R858W) alteration is located in exon 16 (coding exon 15) of the KIAA0319 gene. This alteration results from a C to T substitution at nucleotide position 2572, causing the arginine (R) at amino acid position 858 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
