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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 07, 2022The c.3910C>T (p.R1304C) alteration is located in exon 17 (coding exon 17) of the BAZ1B gene. This alteration results from a C to T substitution at nucleotide position 3910, causing the arginine (R) at amino acid position 1304 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
