Mendeliome v1.2168 PPP2R2B Bryony Thompson edited their review of gene: PPP2R2B: Added comment: 5 cases with NDD and heterozygous missense (4/5 confirmed de novo): p.Thr246Lys (unknown inheritance), p.Asn310Lys (confirmed de novo), p.Glu37Lys (confirmed de novo, also had RNU4-2 path de novo Path variant), p.Ile427Thr (confirmed de novo, also had TAOK1 inherited Path variant), p.Arg149Pro (confirmed de novo). 5/5 with intellectual disability and developmental delay, 4/5 with seizures, 2/5 with hearing loss/auditory neuropathy. Study includes in vitro functional assays supporting a possible loss of function mechanism of disease. The 2 missense with additional diagnoses (E37K & I427T) demonstrated a partial reduction in PP2A holoenzyme assembly. Only 3 cases with a possible diagnosis that could be attributed to the PPP2R2B only, and only 2 were confirmed de novo.; Changed rating: AMBER; Changed publications: 25356899, 39565297; Changed phenotypes: Neurodevelopmental disorder MONDO:0700092
