Collection Method: clinical testing

The c.118G>A (p.V40M) alteration is located in exon 3 (coding exon 3) of the CISD3 gene. This alteration results from a G to A substitution at nucleotide position 118, causing the valine (V) at amino acid position 40 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
