The c.778A>G (p.R260G) alteration is located in exon 2 (coding exon 2) of the HSF5 gene. This alteration results from a A to G substitution at nucleotide position 778, causing the arginine (R) at amino acid position 260 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
