Genes affected

SMARCA5 (HGNC:11101): (SWI/SNF related, matrix associated, actin dependent regulator of chromatin, subfamily a, member 5) The protein encoded by this gene is a member of the SWI/SNF family of proteins. Members of this family have helicase and ATPase activities and are thought to regulate transcription of certain genes by altering the chromatin structure around those genes. The protein encoded by this gene is a component of the chromatin remodeling and spacing factor RSF, a facilitator of the transcription of class II genes by RNA polymerase II. The encoded protein is similar in sequence to the Drosophila ISWI chromatin remodeling protein. [provided by RefSeq, Jul 2008]

The c.488A>G (p.N163S) alteration is located in exon 4 (coding exon 4) of the SMARCA5 gene. This alteration results from a A to G substitution at nucleotide position 488, causing the asparagine (N) at amino acid position 163 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
