General annotation (Comments)
| Tissue specificity | Found in most adult tissues. Down-regulated in a majority of the B-CLL cases examined. Ref.1 |
| Developmental stage | Expressed in fetal liver. |
| Post-translational modification | Phosphorylated upon DNA damage, probably by ATM or ATR. Ref.5 Ref.6 Ref.7 |
| Involvement in disease | 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. Defects in BRWD3 are the cause of mental retardation X-linked type 93 (MRX93) [MIM:300659]; also known as mental retardation X-linked with macrocephaly. Mental retardation is characterized by significantly sub-average general intellectual functioning associated with impairments in adaptative behavior and manifested during the developmental period. Mentally retarded individuals are at least twice as likely to have macrocephaly than are their intellectually normal peers. Ref.8 |
| Sequence similarities | Contains 2 bromo domains. Contains 9 WD repeats. |
| Caution | The translocation involving this gene was originally published as t(X;11)(q13;23) (Ref.1), but BRWD3 is localized to Xq21 and not to Xq13. |
