Genes affected

BAZ1B (HGNC:961): (bromodomain adjacent to zinc finger domain 1B) This gene encodes a member of the bromodomain protein family. The bromodomain is a structural motif characteristic of proteins involved in chromatin-dependent regulation of transcription. This gene is deleted in Williams-Beuren syndrome, a developmental disorder caused by deletion of multiple genes at 7q11.23. [provided by RefSeq, Jul 2008]

The c.4037A>G (p.Q1346R) alteration is located in exon 18 (coding exon 18) of the BAZ1B gene. This alteration results from a A to G substitution at nucleotide position 4037, causing the glutamine (Q) at amino acid position 1346 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
