Genes affected
ZBTB21 (HGNC:13083): (zinc finger and BTB domain containing 21) Enables several functions, including DNA-binding transcription repressor activity, RNA polymerase II-specific; POZ domain binding activity; and methyl-CpG binding activity. Involved in negative regulation of transcription by RNA polymerase II. Located in cytosol and nucleoplasm. [provided by Alliance of Genome Resources, Apr 2022]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 23, 2023The c.2450A>G (p.N817S) alteration is located in exon 3 (coding exon 1) of the ZBTB21 gene. This alteration results from a A to G substitution at nucleotide position 2450, causing the asparagine (N) at amino acid position 817 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
