Genes affected

FOXO1 (HGNC:3819): (forkhead box O1) This gene belongs to the forkhead family of transcription factors which are characterized by a distinct forkhead domain. The specific function of this gene has not yet been determined; however, it may play a role in myogenic growth and differentiation. Translocation of this gene with PAX3 has been associated with alveolar rhabdomyosarcoma. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Uncertain_significance. Variant got 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.27286).

The c.1574C>G (p.P525R) alteration is located in exon 2 (coding exon 2) of the FOXO1 gene. This alteration results from a C to G substitution at nucleotide position 1574, causing the proline (P) at amino acid position 525 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
