Genes affected

SP1 (HGNC:11205): (Sp1 transcription factor) The protein encoded by this gene is a zinc finger transcription factor that binds to GC-rich motifs of many promoters. The encoded protein is involved in many cellular processes, including cell differentiation, cell growth, apoptosis, immune responses, response to DNA damage, and chromatin remodeling. Post-translational modifications such as phosphorylation, acetylation, glycosylation, and proteolytic processing significantly affect the activity of this protein, which can be an activator or a repressor. Three transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Nov 2014]

Ambry Genetics

Sep 20, 2023

The c.74A>G (p.N25S) alteration is located in exon 2 (coding exon 2) of the SP1 gene. This alteration results from a A to G substitution at nucleotide position 74, causing the asparagine (N) at amino acid position 25 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
