The c.980A>G (p.K327R) alteration is located in exon 8 (coding exon 8) of the UPP2 gene. This alteration results from a A to G substitution at nucleotide position 980, causing the lysine (K) at amino acid position 327 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
