The c.59A>G (p.D20G) alteration is located in exon 1 (coding exon 1) of the RPS6KA5 gene. This alteration results from a A to G substitution at nucleotide position 59, causing the aspartic acid (D) at amino acid position 20 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
