The c.1016A>G (p.H339R) alteration is located in exon 10 (coding exon 10) of the CUL2 gene. This alteration results from a A to G substitution at nucleotide position 1016, causing the histidine (H) at amino acid position 339 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
