The c.265G>A (p.V89I) alteration is located in exon 4 (coding exon 4) of the SCFD1 gene. This alteration results from a G to A substitution at nucleotide position 265, causing the valine (V) at amino acid position 89 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
