Collection Method: clinical testing

The c.373C>T (p.P125S) alteration is located in exon 3 (coding exon 3) of the OAF gene. This alteration results from a C to T substitution at nucleotide position 373, causing the proline (P) at amino acid position 125 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
