The c.364G>A (p.G122S) alteration is located in exon 5 (coding exon 5) of the UPP2 gene. This alteration results from a G to A substitution at nucleotide position 364, causing the glycine (G) at amino acid position 122 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
