The c.880G>A (p.G294S) alteration is located in exon 9 (coding exon 9) of the FAM92B gene. This alteration results from a G to A substitution at nucleotide position 880, causing the glycine (G) at amino acid position 294 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
