Genes affected

SAFB2 (HGNC:21605): (scaffold attachment factor B2) The protein encoded by this gene, along with its paralog (scaffold attachment factor B1), is a repressor of estrogen receptor alpha. The encoded protein binds scaffold/matrix attachment region (S/MAR) DNA and is involved in cell cycle regulation, apoptosis, differentiation, the stress response, and regulation of immune genes.

The c.2534G>A (p.R845H) alteration is located in exon 19 (coding exon 19) of the SAFB2 gene. This alteration results from a G to A substitution at nucleotide position 2534, causing the arginine (R) at amino acid position 845 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
