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.931G>T (p.V311L) alteration is located in exon 3 (coding exon 3) of the SP1 gene. This alteration results from a G to T substitution at nucleotide position 931, causing the valine (V) at amino acid position 311 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
