Genes affected

STOX1 (HGNC:23508): (storkhead box 1) Enables RNA polymerase II transcription regulatory region sequence-specific DNA binding activity. Involved in several processes, including positive regulation of G2/M transition of mitotic cell cycle; positive regulation of protein phosphorylation; and regulation of gene expression. Located in centrosome; cytosol; and nuclear lumen. Implicated in pre-eclampsia. Biomarker of Alzheimer's disease. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Uncertain_significance. Variant got 2 ACMG points.

• PP3: MetaRNN computational evidence supports a deleterious effect, 0.883

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.195G>C (p.W65C) alteration is located in exon 1 (coding exon 1) of the STOX1 gene. This alteration results from a G to C substitution at nucleotide position 195, causing the tryptophan (W) at amino acid position 65 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
