Variant summary
Our verdict is Uncertain significance. Variant got 5 ACMG points: 5P and 0B. PM2PM5PP2
The NM_007327.4(GRIN1):c.2530C>A(p.Arg844Ser) variant causes a missense change. The variant was absent in control chromosomes in GnomAD project. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R844C) has been classified as Likely pathogenic.

Genes affected
GRIN1 (HGNC:4584): (glutamate ionotropic receptor NMDA type subunit 1) The protein encoded by this gene is a critical subunit of N-methyl-D-aspartate receptors, members of the glutamate receptor channel superfamily which are heteromeric protein complexes with multiple subunits arranged to form a ligand-gated ion channel. These subunits play a key role in the plasticity of synapses, which is believed to underlie memory and learning. Cell-specific factors are thought to control expression of different isoforms, possibly contributing to the functional diversity of the subunits. Alternatively spliced transcript variants have been described. [provided by RefSeq, Jul 2008]

ACMG classification
Classification made for transcript
Verdict is Uncertain_significance. Variant got 5 ACMG points.
PM2
Very rare variant in population databases, with high coverage;
PM5
Other missense variant is known to change same aminoacid residue: Variant chr9-137163845-C-T is described in Lovd as [Likely_pathogenic].
PP2
Missense variant in the GRIN1 gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 75 curated pathogenic missense variants (we use a threshold of 10). The gene has 49 curated benign missense variants. Gene score misZ: 6.2157 (above the threshold of 3.09). Trascript score misZ: 6.6419 (above the threshold of 3.09). GenCC associations: The gene is linked to developmental and epileptic encephalopathy 101, neurodevelopmental disorder with or without hyperkinetic movements and seizures, autosomal recessive, autosomal dominant non-syndromic intellectual disability, complex neurodevelopmental disorder, intellectual disability, autosomal dominant 8.
