Genes affected
PPME1 (HGNC:30178): (protein phosphatase methylesterase 1) This gene encodes a protein phosphatase methylesterase localized to the nucleus. The encoded protein acts on the protein phosphatase-2A catalytic subunit and supports the ERK pathway through dephosphorylation of regulatory proteins. It plays a role in malignant glioma progression. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Oct 2012]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 05, 2022The c.293C>A (p.A98E) alteration is located in exon 4 (coding exon 4) of the PPME1 gene. This alteration results from a C to A substitution at nucleotide position 293, causing the alanine (A) at amino acid position 98 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
