The c.880A>C (p.S294R) alteration is located in exon 3 (coding exon 3) of the MEGF9 gene. This alteration results from a A to C substitution at nucleotide position 880, causing the serine (S) at amino acid position 294 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
