Collection Method: clinical testing

The c.538G>A (p.V180M) alteration is located in exon 3 (coding exon 3) of the SARAF gene. This alteration results from a G to A substitution at nucleotide position 538, causing the valine (V) at amino acid position 180 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
