Genes affected

FOS (HGNC:3796): (Fos proto-oncogene, AP-1 transcription factor subunit) The Fos gene family consists of 4 members: FOS, FOSB, FOSL1, and FOSL2. These genes encode leucine zipper proteins that can dimerize with proteins of the JUN family, thereby forming the transcription factor complex AP-1. As such, the FOS proteins have been implicated as regulators of cell proliferation, differentiation, and transformation. In some cases, expression of the FOS gene has also been associated with apoptotic cell death. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Likely_benign. Variant got -6 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.1357471).
• BS2: High AC in GnomAdExome at 5 AD gene.

Ambry Genetics

Dec 07, 2023

The c.752C>T (p.P251L) alteration is located in exon 4 (coding exon 4) of the FOS gene. This alteration results from a C to T substitution at nucleotide position 752, causing the proline (P) at amino acid position 251 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
