Genes affected

BCL7B (HGNC:1005): (BAF chromatin remodeling complex subunit BCL7B) This gene encodes a member of the BCL7 family including BCL7A, BCL7B and BCL7C proteins. This member is BCL7B, which contains a region that is highly similar to the N-terminal segment of BCL7A or BCL7C proteins. The BCL7A protein is encoded by the gene known to be directly involved in a three-way gene translocation in a Burkitt lymphoma cell line. This gene is located at a chromosomal region commonly deleted in Williams syndrome. This gene is highly conserved from C. elegans to human. Multiple alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Oct 2010]

The c.392C>T (p.T131M) alteration is located in exon 4 (coding exon 4) of the BCL7B gene. This alteration results from a C to T substitution at nucleotide position 392, causing the threonine (T) at amino acid position 131 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
