The c.551A>G (p.K184R) alteration is located in exon 8 (coding exon 7) of the RALGPS2 gene. This alteration results from a A to G substitution at nucleotide position 551, causing the lysine (K) at amino acid position 184 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
