The c.4033G>A (p.G1345S) alteration is located in exon 19 (coding exon 19) of the FGD6 gene. This alteration results from a G to A substitution at nucleotide position 4033, causing the glycine (G) at amino acid position 1345 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
