Genes affected

FRS2 (HGNC:16971): (fibroblast growth factor receptor substrate 2) Enables fibroblast growth factor receptor binding activity and neurotrophin TRKA receptor binding activity. Involved in negative regulation of cardiac muscle cell differentiation. Acts upstream of or within fibroblast growth factor receptor signaling pathway. Located in adherens junction. Biomarker of renal cell carcinoma. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.21601117).

Collection Method: clinical testing

The c.992C>T (p.S331L) alteration is located in exon 10 (coding exon 5) of the FRS2 gene. This alteration results from a C to T substitution at nucleotide position 992, causing the serine (S) at amino acid position 331 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
