Collection Method: clinical testing

The c.615G>C (p.R205S) alteration is located in exon 4 (coding exon 4) of the ZNF222 gene. This alteration results from a G to C substitution at nucleotide position 615, causing the arginine (R) at amino acid position 205 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
