The c.868G>A (p.G290S) alteration is located in exon 4 (coding exon 3) of the C1QTNF9 gene. This alteration results from a G to A substitution at nucleotide position 868, causing the glycine (G) at amino acid position 290 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
