Variant 19-5590333-C-A details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Likely benign. Variant got -6 ACMG points: 0P and 6B. BP4_ModerateBS2

The NM_014649.3(SAFB2):c.2470G>T(p.Gly824Cys) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000329 in 1,610,060 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 12/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. G824S) has been classified as Uncertain significance.

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.

Ambry Genetics

Jul 09, 2021

The c.2470G>T (p.G824C) alteration is located in exon 18 (coding exon 18) of the SAFB2 gene. This alteration results from a G to T substitution at nucleotide position 2470, causing the glycine (G) at amino acid position 824 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
