Genes affected
ST18 (HGNC:18695): (ST18 C2H2C-type zinc finger transcription factor) Enables RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Involved in cytokine-mediated signaling pathway; negative regulation of cell population proliferation; and positive regulation of nitrogen compound metabolic process. Located in nucleus. Part of protein-DNA complex. [provided by Alliance of Genome Resources, Apr 2022]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 16, 2021The c.1939A>G (p.T647A) alteration is located in exon 16 (coding exon 10) of the ST18 gene. This alteration results from a A to G substitution at nucleotide position 1939, causing the threonine (T) at amino acid position 647 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
