The c.4492G>A (p.V1498I) alteration is located in exon 36 (coding exon 36) of the SLIT3 gene. This alteration results from a G to A substitution at nucleotide position 4492, causing the valine (V) at amino acid position 1498 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
