Variants pathogenicity by type
Statistics on ClinVar variants can assist in determining whether a specific variant type in the WAS 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: Effector protein for Rho-type GTPases that regulates actin filament reorganization via its interaction with the Arp2/3 complex (PubMed:12235133, PubMed:12769847, PubMed:16275905). Important for efficient actin polymerization (PubMed:8625410, PubMed:12235133, PubMed:16275905). Possible regulator of lymphocyte and platelet function (PubMed:9405671). Mediates actin filament reorganization and the formation of actin pedestals upon infection by pathogenic bacteria (PubMed:18650809). In addition to its role in the cytoplasmic cytoskeleton, also promotes actin polymerization in the nucleus, thereby regulating gene transcription and repair of damaged DNA (PubMed:20574068). Promotes homologous recombination (HR) repair in response to DNA damage by promoting nuclear actin polymerization, leading to drive motility of double-strand breaks (DSBs) (PubMed:29925947). {ECO:0000269|PubMed:12235133, ECO:0000269|PubMed:12769847, ECO:0000269|PubMed:16275905, ECO:0000269|PubMed:18650809, ECO:0000269|PubMed:20574068, ECO:0000269|PubMed:29925947, ECO:0000269|PubMed:8625410, ECO:0000269|PubMed:9405671}.;

Note=The disease is caused by mutations affecting the gene represented in this entry.; DISEASE: Thrombocytopenia 1 (THC1) [MIM:313900]: Thrombocytopenia is defined by a decrease in the number of platelets in circulating blood, resulting in the potential for increased bleeding and decreased ability for clotting. {ECO:0000269|PubMed:10447259, ECO:0000269|PubMed:11167787, ECO:0000269|PubMed:11877312, ECO:0000269|PubMed:7795648, ECO:0000269|PubMed:8528199}. Note=The disease is caused by mutations affecting the gene represented in this entry.; DISEASE: Neutropenia, severe congenital, X-linked (XLN) [MIM:300299]: A disorder of hematopoiesis characterized by maturation arrest of granulopoiesis at the level of promyelocytes with peripheral blood absolute neutrophil counts below 0.5 x 10(9)/l and early onset of severe bacterial infections. {ECO:0000269|PubMed:11242115}.
