Genes affected

GRID1 (HGNC:4575): (glutamate ionotropic receptor delta type subunit 1) This gene encodes a subunit of glutamate receptor channels. These channels mediate most of the fast excitatory synaptic transmission in the central nervous system and play key roles in synaptic plasticity.[provided by RefSeq, Jan 2009]

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.82).
• BA1: GnomAd4 highest subpopulation (AMR) allele frequency at 95% confidence interval = 0.212 is higher than 0.05.
