The c.463G>A (p.V155I) alteration is located in exon 4 (coding exon 1) of the GPR19 gene. This alteration results from a G to A substitution at nucleotide position 463, causing the valine (V) at amino acid position 155 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
