Review Status:criteria provided, single submitter
Collection Method:clinical testing

The c.305C>T (p.S102L) alteration is located in exon 4 (coding exon 1) of the PHOSPHO2 gene. This alteration results from a C to T substitution at nucleotide position 305, causing the serine (S) at amino acid position 102 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
