The c.2751G>C (p.K917N) alteration is located in exon 19 (coding exon 18) of the SEMA6A gene. This alteration results from a G to C substitution at nucleotide position 2751, causing the lysine (K) at amino acid position 917 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
