Genes affected
SMARCD1 (HGNC:11106): (SWI/SNF related, matrix associated, actin dependent regulator of chromatin, subfamily d, member 1) 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. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 1 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
PP2
Missense variant in gene, where missense usually causes diseases (based on misZ statistic), SMARCD1. . Gene score misZ 3.4416 (greater than the threshold 3.09). Trascript score misZ 3.2646 (greater than threshold 3.09). GenCC has associacion of gene with Coffin-Siris syndrome 11, autism, susceptibility to, 15, Coffin-Siris syndrome.
BP4
Computational evidence support a benign effect (MetaRNN=0.2543853).

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 23, 2023The c.130C>T (p.P44S) alteration is located in exon 1 (coding exon 1) of the SMARCD1 gene. This alteration results from a C to T substitution at nucleotide position 130, causing the proline (P) at amino acid position 44 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
