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]

The c.245A>G (p.Q82R) alteration is located in exon 3 (coding exon 3) of the SP1 gene. This alteration results from a A to G substitution at nucleotide position 245, causing the glutamine (Q) at amino acid position 82 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
