Review for gene: PPP2R5E was set to RED
Added comment: One 20yrs old individual with learning issues, motor coordination disorders, hypotonia (myopathy on EMG), and behavioural issues (mood and emotional dysregulation). WES testing identified a de novo heterozygous missense variant (Glu191Lys) in PPP2R5E gene. The variant was not found in the 4 healthy brothers of the individual. The variant is located within a conserved LFDSEDPRER motif common to all PPP2R5 B-subunits. Biochemical assays demonstrated a decreased interaction with the PP2A A and C subunits, leading to disturbances in holoenzyme formation.

Protein phosphatase 2A (PP2A) is a family of multifunctional enzymatic complexes crucial for cellular signalling, playing a pivotal role in brain function and development. Mutations in specific genes encoding PP2A complexes have been associated with neurodevelopmental disorders with hypotonia and high risk of seizures (e.g. PP2AR-1A, 2B, 3C, 5C, 5D).
