Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the BRWD3 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: Plays a role in the regulation of cell morphology and cytoskeletal organization. Required in the control of cell shape. {ECO:0000269|PubMed:21834987}.
• Disease: DISEASE: Note=A chromosomal aberration involving BRWD3 can be found in patients with B-cell chronic lymphocytic leukemia (B- CLL). Translocation t(X;11)(q21;q23) with ARHGAP20 does not result in fusion transcripts but disrupts both genes.; DISEASE: Mental retardation, X-linked 93 (MRX93) [MIM:300659]: A disorder characterized by significantly below average general intellectual functioning associated with impairments in adaptive behavior and manifested during the developmental period. Intellectual deficiency is the only primary symptom of non- syndromic X-linked mental retardation, while syndromic mental retardation presents with associated physical, neurological and/or psychiatric manifestations. MRX93 is associated with macrocephaly. {ECO:0000269|PubMed:17668385}. Note=The disease is caused by mutations affecting the gene represented in this entry.
