Collection Method: clinical testing

The c.658A>G (p.M220V) alteration is located in exon 8 (coding exon 8) of the SCFD1 gene. This alteration results from a A to G substitution at nucleotide position 658, causing the methionine (M) at amino acid position 220 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
