Genes affected
PPP2R1A (HGNC:9302): (protein phosphatase 2 scaffold subunit Aalpha) This gene encodes a constant regulatory subunit of protein phosphatase 2. Protein phosphatase 2 is one of the four major Ser/Thr phosphatases, and it is implicated in the negative control of cell growth and division. It consists of a common heteromeric core enzyme, which is composed of a catalytic subunit and a constant regulatory subunit, that associates with a variety of regulatory subunits. The constant regulatory subunit A serves as a scaffolding molecule to coordinate the assembly of the catalytic subunit and a variable regulatory B subunit. This gene encodes an alpha isoform of the constant regulatory subunit A. Alternatively spliced transcript variants have been described. [provided by RefSeq, Apr 2010]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -5 ACMG points.

PP2
Missense variant in gene, where missense usually causes diseases (based on misZ statistic), PPP2R1A. . Gene score misZ 4.4565 (greater than the threshold 3.09). Trascript score misZ 4.3877 (greater than threshold 3.09). GenCC has associacion of gene with intellectual disability, autosomal dominant 40, Houge-Janssens syndrome 2, complex neurodevelopmental disorder.
BP4
Computational evidence support a benign effect (MetaRNN=0.15922007).
BS2
High AC in GnomAdExome4 at 8 AD gene.
