Genes affected

GRIN2B (HGNC:4586): (glutamate ionotropic receptor NMDA type subunit 2B) This gene encodes a member of the N-methyl-D-aspartate (NMDA) receptor family within the ionotropic glutamate receptor superfamily. The encoded protein is a subunit of the NMDA receptor ion channel which acts as an agonist binding site for glutamate. The NMDA receptors mediate a slow calcium-permeable component of excitatory synaptic transmission in the central nervous system. The NMDA receptors are heterotetramers of seven genetically encoded, differentially expressed subunits including NR1 (GRIN1), NR2 (GRIN2A, GRIN2B, GRIN2C, or GRIN2D) and NR3 (GRIN3A or GRIN3B). The early expression of this gene in development suggests a role in brain development, circuit formation, synaptic plasticity, and cellular migration and differentiation. Naturally occurring mutations within this gene are associated with neurodevelopmental disorders including autism spectrum disorder, attention deficit hyperactivity disorder, epilepsy, and schizophrenia.

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -7 ACMG points.

PP2

Missense variant in the GRIN2B gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 135 curated pathogenic missense variants (we use a threshold of 10). The gene has 118 curated benign missense variants. Gene score misZ: 5.4168 (above the threshold of 3.09). Trascript score misZ: 7.3273 (above the threshold of 3.09). GenCC associations: The gene is linked to autism susceptibility 1, developmental and epileptic encephalopathy, 27, autosomal dominant non-syndromic intellectual disability, complex neurodevelopmental disorder, West syndrome, intellectual disability, autosomal dominant 6.

BP4

Computational evidence support a benign effect (MetaRNN=0.20476821).

BP6

Variant 12-13563009-G-A is Benign according to our data. Variant chr12-13563009-G-A is described in ClinVar as [Benign]. Clinvar id is 577792.Status of the report is criteria_provided_single_submitter, 1 stars.

BS2

High AC in GnomAdExome4 at 15 AD gene.
