The c.2389G>A (p.V797I) alteration is located in exon 18 (coding exon 18) of the STRN3 gene. This alteration results from a G to A substitution at nucleotide position 2389, causing the valine (V) at amino acid position 797 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
