The c.610G>A (p.G204S) alteration is located in exon 2 (coding exon 1) of the USP51 gene. This alteration results from a G to A substitution at nucleotide position 610, causing the glycine (G) at amino acid position 204 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
