Genes affected

BRD7 (HGNC:14310): (bromodomain containing 7) This gene encodes a protein which is a member of the bromodomain-containing protein family. The product of this gene has been identified as a component of one form of the SWI/SNF chromatin remodeling complex, and as a protein which interacts with p53 and is required for p53-dependent oncogene-induced senescence which prevents tumor growth. Pseudogenes have been described on chromosomes 2, 3, 6, 13 and 14. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2010]

The c.406C>G (p.L136V) alteration is located in exon 4 (coding exon 4) of the BRD7 gene. This alteration results from a C to G substitution at nucleotide position 406, causing the leucine (L) at amino acid position 136 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
