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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 17, 2023The c.362C>T (p.A121V) alteration is located in exon 3 (coding exon 3) of the SP4 gene. This alteration results from a C to T substitution at nucleotide position 362, causing the alanine (A) at amino acid position 121 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
