Ambry Genetics

Dec 06, 2022

The c.611G>A (p.R204Q) alteration is located in exon 3 (coding exon 3) of the PPM1H gene. This alteration results from a G to A substitution at nucleotide position 611, causing the arginine (R) at amino acid position 204 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
