The c.4379G>A (p.R1460Q) alteration is located in exon 37 (coding exon 37) of the SLIT1 gene. This alteration results from a G to A substitution at nucleotide position 4379, causing the arginine (R) at amino acid position 1460 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
