The c.440A>G (p.K147R) alteration is located in exon 3 (coding exon 3) of the ARRDC2 gene. This alteration results from a A to G substitution at nucleotide position 440, causing the lysine (K) at amino acid position 147 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
