Genes affected

WEE1 (HGNC:12761): (WEE1 G2 checkpoint kinase) This gene encodes a nuclear protein, which is a tyrosine kinase belonging to the Ser/Thr family of protein kinases. This protein catalyzes the inhibitory tyrosine phosphorylation of CDC2/cyclin B kinase, and appears to coordinate the transition between DNA replication and mitosis by protecting the nucleus from cytoplasmically activated CDC2 kinase.

ACMG classification

Verdict is Likely_benign. Variant got -6 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.21326646).
• BS2: High AC in GnomAdExome4 at 11 AD gene.

The c.13A>G (p.S5G) alteration is located in exon 1 (coding exon 1) of the WEE1 gene. This alteration results from a A to G substitution at nucleotide position 13, causing the serine (S) at amino acid position 5 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
