The c.1254G>T (p.K418N) alteration is located in exon 9 (coding exon 9) of the SEPT11 gene. This alteration results from a G to T substitution at nucleotide position 1254, causing the lysine (K) at amino acid position 418 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
