Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the PIK3R1 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: Binds to activated (phosphorylated) protein-Tyr kinases, through its SH2 domain, and acts as an adapter, mediating the association of the p110 catalytic unit to the plasma membrane. Necessary for the insulin-stimulated increase in glucose uptake and glycogen synthesis in insulin-sensitive tissues. Plays an important role in signaling in response to FGFR1, FGFR2, FGFR3, FGFR4, KITLG/SCF, KIT, PDGFRA and PDGFRB. Likewise, plays a role in ITGB2 signaling (PubMed:17626883, PubMed:19805105, PubMed:7518429). Modulates the cellular response to ER stress by promoting nuclear translocation of XBP1 isoform 2 in a ER stress- and/or insulin-dependent manner during metabolic overloading in the liver and hence plays a role in glucose tolerance improvement (PubMed:20348923). {ECO:0000269|PubMed:17626883, ECO:0000269|PubMed:19805105, ECO:0000269|PubMed:20348923, ECO:0000269|PubMed:7518429}.
• Disease: DISEASE: Agammaglobulinemia 7, autosomal recessive (AGM7) [MIM:615214]: A primary immunodeficiency characterized by profoundly low or absent serum antibodies and low or absent circulating B-cells due to an early block of B-cell development. Affected individuals develop severe infections in the first years of life. {ECO:0000269|PubMed:22351933}. Note=The disease is caused by mutations affecting the gene represented in this entry.; DISEASE: SHORT syndrome (SHORTS) [MIM:269880]: A rare, multisystem disease characterized by short stature, anomalies of the anterior chamber of the eye, characteristic facial features such as triangular facies, lack of facial fat, and hypoplastic nasal alae with overhanging columella, partial lipodystrophy, hernias, hyperextensibility, and delayed dentition. The clinical phenotype can include insulin resistance, nephrocalcinosis, and hearing deficits. Developmental milestones and cognition are normal. {ECO:0000269|PubMed:23810378, ECO:0000269|PubMed:23810379, ECO:0000269|PubMed:23810382}. Note=The disease is caused by mutations affecting the gene represented in this entry.; DISEASE: Immunodeficiency 36 (IMD36) [MIM:616005]: A primary immunodeficiency characterized by impaired B-cell function, hypogammaglobulinemia and recurrent infections. {ECO:0000269|PubMed:25133428}. Note=The disease is caused by mutations affecting the gene represented in this entry.
