Genes affected

BRD8 (HGNC:19874): (bromodomain containing 8) The protein encoded by this gene interacts with thyroid hormone receptor in a ligand-dependent manner and enhances thyroid hormone-dependent activation from thyroid response elements. This protein contains a bromodomain and is thought to be a nuclear receptor coactivator. Multiple alternatively spliced transcript variants that encode distinct isoforms have been identified.

Ambry Genetics

Apr 13, 2022

The c.2017A>G (p.I673V) alteration is located in exon 15 (coding exon 15) of the BRD8 gene. This alteration results from a A to G substitution at nucleotide position 2017, causing the isoleucine (I) at amino acid position 673 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
