The c.890G>A (p.G297E) alteration is located in exon 3 (coding exon 2) of the MFAP3 gene. This alteration results from a G to A substitution at nucleotide position 890, causing the glycine (G) at amino acid position 297 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
