Collection Method: clinical testing

The c.2051G>A (p.R684H) alteration is located in exon 3 (coding exon 2) of the FIGN gene. This alteration results from a G to A substitution at nucleotide position 2051, causing the arginine (R) at amino acid position 684 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
