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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 14, 2021The c.2692G>T (p.V898L) alteration is located in exon 21 (coding exon 21) of the BRD8 gene. This alteration results from a G to T substitution at nucleotide position 2692, causing the valine (V) at amino acid position 898 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
