Genes affected

RSF1 (HGNC:18118): (remodeling and spacing factor 1) This gene encodes a nuclear protein that interacts with hepatitis B virus X protein (HBX) and facilitates transcription of hepatitis B virus genes by the HBX transcription activator, suggesting a role for this interaction in the virus life cycle. This protein also interacts with SNF2H protein to form the RSF chromatin-remodeling complex, where the SNF2H subunit functions as the nucleosome-dependent ATPase, and this protein as the histone chaperone.

The c.4243G>A (p.A1415T) alteration is located in exon 16 (coding exon 16) of the RSF1 gene. This alteration results from a G to A substitution at nucleotide position 4243, causing the alanine (A) at amino acid position 1415 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
