Genes affected

TAOK3 (HGNC:18133): (TAO kinase 3) The protein encoded by this gene is a serine/threonine protein kinase that activates the p38/MAPK14 stress-activated MAPK cascade but inhibits the basal activity of the MAPK8/JNK cascade. The encoded protein is a member of the GCK subfamily of STE20-like kinases. [provided by RefSeq, Oct 2016]

The c.1868G>A (p.R623Q) alteration is located in exon 17 (coding exon 15) of the TAOK3 gene. This alteration results from a G to A substitution at nucleotide position 1868, causing the arginine (R) at amino acid position 623 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
