The c.4351G>C (p.E1451Q) alteration is located in exon 36 (coding exon 36) of the SLIT1 gene. This alteration results from a G to C substitution at nucleotide position 4351, causing the glutamic acid (E) at amino acid position 1451 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
