The c.3899G>A (p.R1300H) alteration is located in exon 35 (coding exon 35) of the SLIT1 gene. This alteration results from a G to A substitution at nucleotide position 3899, causing the arginine (R) at amino acid position 1300 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
