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

Dec 14, 2021

The c.3250C>A (p.L1084I) alteration is located in exon 23 (coding exon 23) of the BRD8 gene. This alteration results from a C to A substitution at nucleotide position 3250, causing the leucine (L) at amino acid position 1084 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
