The c.469G>C (p.E157Q) alteration is located in exon 2 (coding exon 1) of the FIGNL2 gene. This alteration results from a G to C substitution at nucleotide position 469, causing the glutamic acid (E) at amino acid position 157 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
