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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 16, 2021The c.2827C>G (p.P943A) alteration is located in exon 21 (coding exon 21) of the SAFB2 gene. This alteration results from a C to G substitution at nucleotide position 2827, causing the proline (P) at amino acid position 943 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
