The c.688G>A (p.E230K) 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 688, causing the glutamic acid (E) at amino acid position 230 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
