Collection Method: clinical testing

The c.214A>G (p.M72V) alteration is located in exon 2 (coding exon 1) of the RNF220 gene. This alteration results from a A to G substitution at nucleotide position 214, causing the methionine (M) at amino acid position 72 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
