Ambry Genetics

Nov 29, 2023

The c.635A>G (p.Q212R) alteration is located in exon 4 (coding exon 4) of the PPM1M gene. This alteration results from a A to G substitution at nucleotide position 635, causing the glutamine (Q) at amino acid position 212 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
