Genes affected

FYN (HGNC:4037): (FYN proto-oncogene, Src family tyrosine kinase) This gene is a member of the protein-tyrosine kinase oncogene family. It encodes a membrane-associated tyrosine kinase that has been implicated in the control of cell growth. The protein associates with the p85 subunit of phosphatidylinositol 3-kinase and interacts with the fyn-binding protein. Alternatively spliced transcript variants encoding distinct isoforms exist.

ACMG classification

Verdict is Uncertain_significance. Variant got 5 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant where missense usually causes diseases, FYN
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.907

The c.1103T>C (p.V368A) alteration is located in exon 1 (coding exon 1) of the FYN gene. This alteration results from a T to C substitution at nucleotide position 1103, causing the valine (V) at amino acid position 368 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
