The c.1483G>A (p.G495R) alteration is located in exon 11 (coding exon 11) of the ADGRL4 gene. This alteration results from a G to A substitution at nucleotide position 1483, causing the glycine (G) at amino acid position 495 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
