Collection Method: clinical testing

The c.1654G>A (p.V552M) alteration is located in exon 10 (coding exon 9) of the FSD2 gene. This alteration results from a G to A substitution at nucleotide position 1654, causing the valine (V) at amino acid position 552 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
