The c.1726G>A (p.G576S) alteration is located in exon 17 (coding exon 17) of the ITFG1 gene. This alteration results from a G to A substitution at nucleotide position 1726, causing the glycine (G) at amino acid position 576 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
