Collection Method: clinical testing

The c.605A>T (p.Y202F) alteration is located in exon 4 (coding exon 1) of the PHOSPHO2 gene. This alteration results from a A to T substitution at nucleotide position 605, causing the tyrosine (Y) at amino acid position 202 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
