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.

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.12655914).

The c.1828T>G (p.S610A) alteration is located in exon 14 (coding exon 14) of the BRD8 gene. This alteration results from a T to G substitution at nucleotide position 1828, causing the serine (S) at amino acid position 610 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
