The c.770A>G (p.K257R) alteration is located in exon 7 (coding exon 7) of the RUNDC3A gene. This alteration results from a A to G substitution at nucleotide position 770, causing the lysine (K) at amino acid position 257 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
