The c.1052A>G (p.K351R) alteration is located in exon 4 (coding exon 1) of the GPR19 gene. This alteration results from a A to G substitution at nucleotide position 1052, causing the lysine (K) at amino acid position 351 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
