The c.4246G>A (p.G1416R) alteration is located in exon 36 (coding exon 36) of the SLIT1 gene. This alteration results from a G to A substitution at nucleotide position 4246, causing the glycine (G) at amino acid position 1416 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
