Collection Method:clinical testing

The c.50A>G (p.N17S) alteration is located in exon 4 (coding exon 1) of the PHOSPHO2 gene. This alteration results from a A to G substitution at nucleotide position 50, causing the asparagine (N) at amino acid position 17 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
