Genes affected

BRMS1L (HGNC:20512): (BRMS1 like transcriptional repressor) The protein encoded by this gene shows sequence similarity to the human breast carcinoma metastasis suppressor (BRMS1) protein and the mammalian Sds3 (suppressor of defective silencing 3) proteins. This protein is a component of the mSin3a family of histone deacetylase complexes (HDAC). [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Uncertain_significance. Variant got 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage

Oct 30, 2023

The c.793G>T (p.G265C) alteration is located in exon 9 (coding exon 9) of the BRMS1L gene. This alteration results from a G to T substitution at nucleotide position 793, causing the glycine (G) at amino acid position 265 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
