Ambry Genetics

Aug 30, 2022

The c.742C>T (p.P248S) alteration is located in exon 5 (coding exon 5) of the PPM1M gene. This alteration results from a C to T substitution at nucleotide position 742, causing the proline (P) at amino acid position 248 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
