Collection Method: clinical testing

The c.1435C>A (p.Q479K) alteration is located in exon 3 (coding exon 2) of the FIGN gene. This alteration results from a C to A substitution at nucleotide position 1435, causing the glutamine (Q) at amino acid position 479 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
