Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 28, 2024The c.575T>G (p.L192W) alteration is located in exon 3 (coding exon 3) of the PPM1M gene. This alteration results from a T to G substitution at nucleotide position 575, causing the leucine (L) at amino acid position 192 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
