ClinVar

This is a list of variants' phenotypes submitted to ClinVar and linked to the GIGYF2 gene.

Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the GIGYF2 gene is commonly pathogenic or not.

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: Key component of the 4EHP-GYF2 complex, a multiprotein complex that acts as a repressor of translation initiation (PubMed:22751931). In 4EHP-GYF2 the complex, acts as a factor that bridges EIF4E2 to ZFP36/TTP, linking translation repression with mRNA decay (By similarity). May act cooperatively with GRB10 to regulate tyrosine kinase receptor signaling, including IGF1 and insulin receptors (PubMed:12771153). {ECO:0000250|UniProtKB:Q6Y7W8, ECO:0000269|PubMed:12771153, ECO:0000269|PubMed:22751931}.
• Disease: DISEASE: Parkinson disease 11 (PARK11) [MIM:607688]: A complex neurodegenerative disorder characterized by bradykinesia, resting tremor, muscular rigidity and postural instability, as well as by a clinically significant response to treatment with levodopa. The pathology involves the loss of dopaminergic neurons in the substantia nigra and the presence of Lewy bodies (intraneuronal accumulations of aggregated proteins), in surviving neurons in various areas of the brain. {ECO:0000269|PubMed:18358451, ECO:0000269|PubMed:20060621, ECO:0000269|PubMed:20178831, ECO:0000269|PubMed:26134514}. Note=Disease susceptibility may be associated with variations affecting the gene represented in this entry. Its association with Parkinson disease is however unclear. According to a number of studies, variations affecting this gene are not a frequent cause of Parkinson disease, suggesting that GIGYF2 does not play a major role in Parkinson disease etiology (PubMed:19279319, PubMed:19429085, PubMed:19638301, PubMed:19482505, PubMed:20004041, PubMed:19321232, PubMed:20060621). {ECO:0000269|PubMed:19279319, ECO:0000269|PubMed:19321232, ECO:0000269|PubMed:19429085, ECO:0000269|PubMed:19482505, ECO:0000269|PubMed:19638301, ECO:0000269|PubMed:20004041, ECO:0000269|PubMed:20060621}.
