Genes affected

SMARCD3 (HGNC:11108): (SWI/SNF related, matrix associated, actin dependent regulator of chromatin, subfamily d, member 3) 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. Multiple alternatively spliced transcript variants have been found for this gene, but the biological validity of some variants has not been determined. [provided by RefSeq, Jul 2008]

The c.1144C>G (p.Q382E) alteration is located in exon 10 (coding exon 10) of the SMARCD3 gene. This alteration results from a C to G substitution at nucleotide position 1144, causing the glutamine (Q) at amino acid position 382 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
