GRINdb

GRINdb curates and aggregates genetic, functional, and clinical variant data for GRIN genes encoding N-methyl-D-aspartate receptor (NMDAR) subunits to support interpretation of variants affecting glutamatergic neurotransmission.

Key Features:

• Curated Repository: Consolidates data from over 4,000 GRIN variants into a unified, nonredundant collection of genetic, functional, and clinical information.
• Clinical Relevance: Supports molecular stratification of patients with GRIN-related disorders (GRDs), including rare pediatric neurological conditions caused by NMDAR dysfunction.
• Pathogenicity Mapping: Maps genetic and clinical information of GRIN variants onto the N-methyl-D-aspartate receptor (NMDAR) structure to reveal differences in pathogenicity and associated clinical phenotypes.
• Facilitates Patient Stratification: Bridges variant identification and patient stratification to inform molecular clinical advice and research into GRDs.

Scientific Applications:

• Genotype–Phenotype Correlation: Enables analysis of correlations between specific GRIN variants and clinical phenotypes in GRDs.
• Functional Impact Investigation: Supports investigation of the functional consequences of individual GRIN variants on NMDAR subunits.
• Therapeutic Strategy Development: Provides variant-level data to inform development of targeted therapeutic strategies for NMDAR-related pathologies.
• Clinical Interpretation: Informs diagnostic assessment and personalized treatment planning through integrated genetic, functional, and clinical evidence.

Methodology:

Rigorous manual curation of genetic, clinical, and functional data for GRIN gene variants; mapping of genetic and clinical variant data onto N-methyl-D-aspartate receptor (NMDAR) structural models.
