The c.2872A>C (p.N958H) alteration is located in exon 19 (coding exon 18) of the SEMA6A gene. This alteration results from a A to C substitution at nucleotide position 2872, causing the asparagine (N) at amino acid position 958 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
