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.2451C>A (p.D817E) alteration is located in exon 18 (coding exon 18) of the SAFB2 gene. This alteration results from a C to A substitution at nucleotide position 2451, causing the aspartic acid (D) at amino acid position 817 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
