The c.685T>G (p.F229V) alteration is located in exon 3 (coding exon 3) of the PPM1H gene. This alteration results from a T to G substitution at nucleotide position 685, causing the phenylalanine (F) at amino acid position 229 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
