Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 31, 2022The c.1430G>A (p.R477H) alteration is located in exon 10 (coding exon 10) of the PPM1H gene. This alteration results from a G to A substitution at nucleotide position 1430, causing the arginine (R) at amino acid position 477 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
