Genes affected

SP4 (HGNC:11209): (Sp4 transcription factor) The protein encoded by this gene is a transcription factor that can bind to the GC promoter region of a variety of genes, including those of the photoreceptor signal transduction system. The encoded protein binds to the same sites in promoter CpG islands as does the transcription factor SP1, although its expression is much more restricted compared to that of SP1. This gene may be involved in bipolar disorder and schizophrenia. [provided by RefSeq, May 2016]

Collection Method: clinical testing

The c.32A>C (p.E11A) alteration is located in exon 2 (coding exon 2) of the SP4 gene. This alteration results from a A to C substitution at nucleotide position 32, causing the glutamic acid (E) at amino acid position 11 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
