Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the GRIP1 gene is commonly pathogenic or not. These statistics are base on transcript: NM_001366722.1. Only rare variants are included in the table.

In the table, we include only reliable ClinVar variants with their consequences to MANE Select, Mane Plus Clinical transcripts, or transcripts with TSL equals 1. Click the count to view the source variants.

Warning: slight differences between displayed counts and the number of variants in ClinVar may occur, primarily due to (1) the application of a different transcript and/or consequence by our variant effect predictor or (2) differences in clinical significance: we classify Benign/Likely benign variants as Likely benign and Pathogenic/Likely pathogenic variants as Likely pathogenic.

• Function: FUNCTION: May play a role as a localized scaffold for the assembly of a multiprotein signaling complex and as mediator of the trafficking of its binding partners at specific subcellular location in neurons (PubMed:10197531). Through complex formation with NSG1, GRIA2 and STX12 controls the intracellular fate of AMPAR and the endosomal sorting of the GRIA2 subunit toward recycling and membrane targeting (By similarity). {ECO:0000250|UniProtKB:P97879, ECO:0000269|PubMed:10197531}.
• Disease: DISEASE: Fraser syndrome 3 (FRASRS3) [MIM:617667]: A form of Fraser syndrome, an autosomal recessive disorder characterized by cryptophthalmos, cutaneous syndactyly, and urogenital abnormalities including renal agenesis or hypoplasia. Additional features include abnormalities of the larynx, ear malformations, and facial abnormalities. {ECO:0000269|PubMed:22510445}. Note=The disease is caused by mutations affecting the gene represented in this entry.
