Collection Method: clinical testing

The c.15718G>A (p.G5240S) alteration is located in exon 34 (coding exon 34) of the FCGBP gene. This alteration results from a G to A substitution at nucleotide position 15718, causing the glycine (G) at amino acid position 5240 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
