Aug 21, 2024

The c.638A>C (p.Q213P) alteration is located in exon 4 (coding exon 1) of the PHOSPHO2 gene. This alteration results from a A to C substitution at nucleotide position 638, causing the glutamine (Q) at amino acid position 213 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
