Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 09, 2024The c.436C>T (p.R146W) alteration is located in exon 3 (coding exon 3) of the PPM1M gene. This alteration results from a C to T substitution at nucleotide position 436, causing the arginine (R) at amino acid position 146 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
