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]

ACMG classification

Verdict is Likely_pathogenic. Variant got 8 ACMG points.

• PM1: In a active_site Proton acceptor (size 0) in uniprot entity STK24_HUMAN
• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.965

The c.502G>A (p.G168S) alteration is located in exon 5 (coding exon 5) of the STK24 gene. This alteration results from a G to A substitution at nucleotide position 502, causing the glycine (G) at amino acid position 168 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
