Genes affected

SMARCD2 (HGNC:11107): (SWI/SNF related, matrix associated, actin dependent regulator of chromatin, subfamily d, member 2) The protein encoded by this gene is a member of the SWI/SNF family of proteins, whose members display helicase and ATPase activities and which are thought to regulate transcription of certain genes by altering the chromatin structure around those genes. The encoded protein is part of the large ATP-dependent chromatin remodeling complex SNF/SWI and has sequence similarity to the yeast Swp73 protein. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.54).
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.885 is higher than 0.05.
