The c.1403A>G (p.N468S) alteration is located in exon 6 (coding exon 6) of the MEGF9 gene. This alteration results from a A to G substitution at nucleotide position 1403, causing the asparagine (N) at amino acid position 468 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
