Genes affected

STK24 (HGNC:11403): (serine/threonine kinase 24) This gene encodes a serine/threonine protein kinase that functions upstream of mitogen-activated protein kinase (MAPK) signaling. The encoded protein is cleaved into two chains by caspases; the N-terminal fragment (MST3/N) translocates to the nucleus and promotes programmed cells death. There is a pseudogene for this gene on chromosome X. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Nov 2013]

The c.856A>G (p.I286V) alteration is located in exon 7 (coding exon 7) of the STK24 gene. This alteration results from a A to G substitution at nucleotide position 856, causing the isoleucine (I) at amino acid position 286 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
