Genes affected

FRK (HGNC:3955): (fyn related Src family tyrosine kinase) The protein encoded by this gene belongs to the TYR family of protein kinases. This tyrosine kinase is a nuclear protein and may function during G1 and S phase of the cell cycle and suppress growth. [provided by RefSeq, Jul 2008]

Collection Method: clinical testing

The c.478G>T (p.A160S) alteration is located in exon 3 (coding exon 3) of the FRK gene. This alteration results from a G to T substitution at nucleotide position 478, causing the alanine (A) at amino acid position 160 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
